| Partners contributions: SENSeOR will drive the design of the dedicated RADAR unit. FEMTO-ST will investigate the stability of the commercial RADAR unit and assess means of stabilizing the timebase. TOTAL SA will provide requirements as to the usability of the measurement system used by operator on the ground
Objective: Achieve a usable interrogation system, whether custom or derived from a commercial instrument, including the display of the measured quantity through sensor calibration coefficients Deliverable 3: a Ground Penetrating RADAR unit dedicated to probing cooperative target response in addition to sub-surface interfaces, including the software processing for converting the echo delay difference to a chemical concentration measurement. T0+30 2.1 Assessment of commercially available GPR suitability to sensor interrogation Objective: assess the use of a commercial GPR for sensor interrogation and correct potential flaws. Fig 3 Sensing capability in pure and composite compound mixtures While the aim of the workpackage is to develop a custom GPR unit specifically designed for sensor measurement in addition to sub-surface interface detection, assessing state of the art instrument to these tasks provide the background for further custom developments. Additionally, a commercially available GPR allows for measuring sensors early in the project while the custom instrument is under development. Finally, the commercial GPR is considered as a benchmark when qualifying our custom system. In this workpackage, we define the link budget, replacing the RADAR cross section with the sensor insertion losses (WP1.1 and 1.3) to assess the interrogation range, based on the known receiver stage sensitivity. Interrogation in snow has been demonstrated up to 5 m with lithium niobate transducers21. We emphasize here that the SAW sensor interrogation is an analog process (as opposed to digital communication) and the chemical detection limit will be driven by the signal to noise ratio of the measurement. We are not considering a binary answer to being able or not able to probe the sensor response, but aiming to maximize the signal through state of the art hardware and software processing (matched filter) to enhance the signal to noise ration and hence the detection limit. Since we have already identified timebase drift as a limitation to the use of a commercial GPR, to recover a fine estimate of the acoustic velocity, strategies for mitigating this effect are under investigation and will be implemented during the project, whether through thermal control of the most sensitive elements, timebase measurement in parallel to its generation (to measure the drift and correct it during software post-processing), or offset control. This issue tackles the general problem of interrogation stability: the time of flight measurement requires an accurate time reference on the embedded RADAR electronics, a field of expertise of FEMTO-ST. Finally, once the time delay between echoes has been identified accurately, the dedicated software is upgraded to implement real time signal processing for extracting analyte concentration and displaying the result to the user. All software development will be completed under supervision of Total SA for providing feedback on the needed functionalities and including necessary functionalities in the user interface, in addition to defining requirements of the user on the field. The proexgprcontrol software was specifically designed to acquire data from the commercial GPR unit using low-power embedded computers which can then route the messages over long distance communication schemes (e.g. LORA network) if the system is to be deployed remotedly. 
High Risks: an excessive drift of the stroboscopic time base reference could prevent minute variations of the sensor acoustic velocity from being measured and hence deteriorate the detection limit. Fallback solutions: if hardware control of the timebase drift of the GPR is not efficient enough, we will circumvent this drift by adding a second reference delay line in parallel to the sensing delay line, which will provide an independent measurement of the sampling rate. This additional delay line will lead to a degradation of the coupling factor of the sensor, and hence interrogation range. 2.2 Custom GPR design, including emission and improved reception stages based on existing prototypes Objective: custom GPR specifically designed for acoustic sensor probing. Most commercially available GPR units use a pulsed mode interrogation strategy with a stroboscopic receiver architecture. A classical alternative solution is the Frequency Swept Continuous Wave (FSCW) architecture: selecting the best-suited solution for the current project is investigated at the beginning of this task. Indeed, the pulsed mode approach generates pulses with a spectrum dependent on the properties of the soil under the emitting antenna. However, the acoustic sensor operates in a fixed frequency band determined by the electrode geometry and the piezoelectric substrate acoustic velocity. Since the acoustic sensor exhibits a lower bandwidth than passive interfaces, controlling the spectrum of the emitted pulse is mandatory. The first step of this task is to choose the best architecture between a pulsed mode approach based on an avalanche transistor emitter – as found in the commercial unit investigated in task 2.1 – and a FSCW strategy based on Direct Digital Synthesizer + linear amplifier (at the expense of high power consumption) which is better suited thanks to its precise spectrum occupation control matching the sensor transfer function.. Then, consistent with the emitter and the general interrogation strategy, the receiver either implements a stroboscopic timebase generation (microcontroller based or FPGA based designs) or down-conversion by mixing with the emitter and Fourier transform for frequency to time domain conversion (microcontroller based). While the stroboscopic strategy is the cause of the drift observed with the commercial instrument, we have already demonstrated14 that replacing a voltage to time generator with a quartz-disciplined generator provides the needed stability on the receiver side. A core challenge then, when deciding to design a custom GPR for this application, is fabricating ultrawideband antennas properly shielded from surrounding interferences yet efficiently radiating towards the ground. SENSeOR SAS has extensive expertise in antenna design with two engineers dedicated to this task. The user interface will be inspired and based on the afore-mentioned proexgprcontrol software: the user must be able to control key parameters of the GPR (number of samples, stacking, frequency or time range) and display the measurement results, either in raw format (echoes from the sensor), processed format (time delay between echoes) or as expected by the end-user (analyte concentration). Such processing requires a differential time of flight measurement for getting rid of the RADAR to sensor distance, and usually a temperature estimate of the sensor to allow for extracting a precise acoustic velocity measurement related to the analyte concentration, as will be implemented on the sensor side in WP 1.1. The custom electronics, once able to acquire the signature of the cooperative target and measure the analyte concentration, can be connected to a low power, low bitrate, long range communication network (e.g. LORA) if remote operation is required. Low risks: FSCW is well understood and used in academic GPR demonstrators: the identified risk is the poor interrogation range if measurement parameters are not set properly. Commercial network analyzers are known to be used for GPR purposes. Fallback solutions: the commercial GPR and commercial network analyzers are readily available and can be used as benchmarks. 2.3 Acoustic transducer interrogation using GPR Objective: Antennas are a core element in the link budget. The sub-surface system including the sensor and its radiating antenna will be subject to varying permittivities of the soil. A wideband antenna radiating towards the surface compatible with burying the sensor from the surface with a least invasive operation must be designed. It will be broadband enough to transmit the sensor response. We must fit the sensor on an antenna as insensitive as possible to environmental parameters (e.g. wideband bowtie antenna) for installation in a sub-surface test environment and demonstrate in this controlled environment the analyte concentration measurement capability. Hence, the first aim of this task is to design the antenna supporting the sensor and compatible with an installation underground -- modeling of the antenna behavior in complex media is investigated using the GPRMax software whose operation is already well understood by SENSeOR and FEMTO-ST. Additional constraint with respect to the classical antenna design approach includes on the one hand reducing the sensitivity of the antenna transfer function to varying surrounding dielectric conditions – the frequency band of the sensor should remain properly coupled to the antenna whether the soil is wet or dry – and new geometrical constraints since the antenna is no longer lying flat on the ground surface but is buried. Since the easiest way of installing the sensor would be coring, a cylindrical geometry with the radiation pattern focusing towards the surface would be well suited. Examples of ultra-wideband antenna designs meeting this constraint are the conical spiral metal strip antenna, e.g. exhibited in Fig. 11.4 of 23. Having designed the antenna and fitted the packaged sensor for a complete setup ready to be installed in soil, we aim at the experimental demonstration of interrogation characteristics: measurement range and resolution. Again, let us emphasize that the acoustic transducer is an analog transducer: the returned echoes convey the chemical concentration information through an echo delay, whose timing resolution is determined by the signal to noise ratio: the better the link budget, the more accurate the reading. A degraded link budget will not prevent the measurement, as would be the case with a digital system – piezoelectricity being a linear process, some power will always be returned to the RADAR receiver, with the challenge of implementing the appropriate signal processing steps to extract the echo signal from noise (tasks 2.1&2.2). Since a differential approach is used in which multiple echoes are returned by the sensor, all of which have been triggered by the same incoming pulse, the current approach of cross-correlation (or auto-correlation if no windowing assumption is done) meets the matched filter requirement and is arguably the most efficient solution. Minor risks: antenna geometry is a tradeoff between deployment constraints and radiation efficiency. The basic dipole is unfavorable because it must lie horizontal when buried, hence requiring coring a hole as wide as the dipole is long. While hardly practical, this approach is the one currently used with a 50-cm long bowtie antenna operating in the 100-200 MHz range. Fallback solutions: finding a more favorable geometry would ease deployment. Using a less favorable geometry from a deployment perspective, yet allowing a sufficient link budget for the GPR located on the surface to recover a usable signal when illuminating the sensor. Work package 3. Sensor testing and validation in real world environments, T0 +30 - T0 +48 Leader: M.F. Bénassy (TOTAL SA) Personel involved: F. Chérioux, and J.-M. Friedt (FEMTO-ST) – D. Rabus, F. Gegot (SENSeOR) – M. Baqué, I. Betremieux and M.F. Bénassy (TOTAL SA) Partners contributions: SENSeOR will provide the functionalized transducers for testing as well as the reader unit (GPR). FEMTO-ST provides a laboratory tested for assessing the sensor response in a controlled laboratory environment (sandbox). TOTAL SA will provide relevant infrastructures for testing the sensor a representative industrial environment and assessing the response under simple and complex hydrocarbon compound mixtures. Objective: assess detection limits, selectivity, sensitivity and usability of the integrated system. Deliverable 4: Demonstration of the detection of the targeted analyses in a sub-surface environment of a site of the TOTAL SA group. T0+42 Objectives: 1) To demonstrate the measurement capability in a complex mixture and to calibrate detection limits in a laboratory environment, 2) Sensor deployment in a relevant industrial environment. The WP3 is devoted to the testing of the whole system in a real-world environment. The initial step will be the demonstration of the sensing detection in outdoor conditions. To achieve that demonstration, we will deploy our system in a sandbox. The sandbox experiment aims at exposing the sensor to outdoor conditions representative of deployment sites (varying concentrations of analytes, varying temperatures and stress etc.) We have already obtained the authorization of the ENSMM (where part of the FEMTO-ST Institute staff is hosted) and secured funding for the assembly of the sandbox thanks to the high-expected impacts of UNDERGROUND. 
In parallel, tests with controlled compound mixtures aim at assessing the selectivity and complementing sensitivity tests with varying concentrations: such analysis will be performed in the TOTAL SA analytical chemistry facilities in Lacq. Upon validation of the system operating principle and deployment capability, we will deploy the system on a representative industrial site operated by TOTAL SA. This deployment will be helpful to acquire measurements in an environment representative of industrial sites, and to have some feedback from endusers on the usability of the system.

Impact and benefits of the project III.1 Scientific, economic and social impacts For two decades, the pollution of soils and groundwater has become a major burning topics because of the risks for the future generation health. Due to the scale and variety of industries, addressing pollution problems from industrial estates can be a challenging task. The key interventions in this area involve working with local governments, non-governmental organisations, and industry leaders to improve the levels of control, treatment facilities, and health and safety management at the estates. UNDERGROUND, aiming to develop a complete system for monitoring sub-surface pollution risks in oil industry infrastructures using passive sensors and GPR interrogation, fully fits the major societal and economic challenge. From a technological perspective, deliverables of this project will be between the proofs of concept (TRL 3) and prototype demonstration in relevant environment (TRL 6). This range of TRL is in adequation with the PRCE call provided by the ANR and with the skills and facilities of the three partners involved in UNDERGROUND. For the point of view of SENSeOR SAS, thanks to the UNDERGROUND project results, we will be able to enlarge our product portfolio with wireless and passive SAW chemical sensors: today SENSeOR is selling SAW temperature sensors and is developing SAW stress sensors. Wireless stress and temperature sensors, whatever the technology is, represent around 25% in revenues of the wireless sensors market: bio and chemical wireless sensors represent around 20% in revenues of this market and are therefore of strategic importance for SENSeOR. At the end of the UNDERGROUND project, if the results are successful, SENSeOR will reinforce its development team in Besançon with the objective of hiring 2 people: one engineer in charge of further development of the prototype and one technician for tests & validation tasks. TOTAL has the ambition to become the major for responsible energy. Safety is set as a group value and operating in a way to minimize our impact is a priority actions principle. Many monitoring, for sites emissions are on place, either through voluntary commitments or to comply with regulations. Soil pollution is difficult to address: emissions points are not visible, the area to cover is usually wide. Today, a specific monitoring campaign, with sampling and laboratory analysis is the only way to have a realistic estimate of the soils quality. It is time consuming, expensive and results are not instantaneous. The UNDERGROUND project will offer a unique opportunity to have a soil survey, offering possibility to have a time followup, and estimate the cumulative value of soil pollution. These sensors of high performances will be easy to install, maintenance free, and shall promote safety of our assets by following regularly our potential losses and reducing our impact much quicker. Passive and autonomous sensors is a must to be able to install them in existing sites, where infrastructure has not been designed for soils survey from the beginning.
The expected impacts of UNDERGROUND fit the challenge 7 (défi 7) of the 2016 action plan of the ANR devoted to Innovative and communication society, theme 8 entitled “Micro- and nanotechnologies for information and communication processing”. Indeed, the development of autonomous systems (such as passive sensors and associated interrogation unit) is one of the main objectives of the challenge 7, themes 8, as described in the work programme 2017 of the ANR. UNDERGROUND is in adequacy with the orientation 26&27 of the SNR. In addition, the objectives of the UNDERGROUND project impact two of the six Key Enabling Technologies, i. e. nanotechnology and advanced materials, as defined by European Commission in the framework programme for research and innovation (H2020). Indeed, the strategy defined in the framework of the UNDERGROUND project aims at combining expertise in chemistry, electronics, acoustics and cleanroom manufacturing. The ANR grant will allow the three partners to reach a position of leader in these fields. The FEMTO-ST institute will develop new knowledge on acoustic transducers acting as passive sensors, ground penetrating RADAR instrumentation and innovative materials for cleanroom compatible micro- and nanofabrication.
Patent applications within the project are foreseeable, for instance, concerning new systems for System for monitoring sub-surface pollution risks in oil industry infrastructures using passive sensors, only from an upstream research point of view, but also in a race to novel applications that could fuel economy and industry in the future. Developing a convincing patent portfolio will be of prior importance, when application for more application-oriented projects will be made, when building partnerships with other institutions and/or industrial partners, and in the event of the creation of a spin-off company. The latter could hire non-permanent staff involved in the project, and would benefit from the 20-years-experience at FEMTO-ST, which was acknowledged by an award from the INPI (National Institute for Intellectual Property) in 2011. In practice, the assignment of the results’ ownership will be to the party or the parties which have contributed to those results. The co-owner parties of the patentable joint results shall decide whether the latter shall be subject to patent applications filed/registered in their joint names and shall designate the party from amongst them which shall be responsible for accomplishing the filing/registration formalities and for maintaining the patent in force, and the patents application to the joint names of all concerned partners. All publications drafts about the results shall be submitted to the others partners prior to the publication. Partners may object to publication if they consider that their results’ protection could therefore be affected. After considering patenting possibilities, communications of the results will be performed via publications in international peer-reviewed scientific journals of highest impact, both broad audience ones and more specialized ones. The manuscripts will be made accessible in open archives like HAL and arXiv. Key results will be further popularized with the help of the communication department of the CNRS. A second medium for communicating the results will be obviously in the form of presentations to national and international scientific events (e.g. ADIPEC – Abu Dhabi International Petroleum Exhibition and Conference, GPR Conference, EMRS meeting, Congrès Général de la SFP, International Workshop on Advanced GPR, ACS meetings, APS March meeting, etc.). III.4. Popularization of the project's outcomes towards a broader audience We plan an action towards the broader audience. The first one is a mobile experiment illustrating the ability to interrogate passive cooperative targets through a wireless link24. A 2,000 euros sum is requested to the ANR for this purpose (see request from FEMTO-ST). Dedicated experiments illustrating how acoustic transducers are used to delay the incoming electromagnetic pulse and separate the sensor signal from clutter, in a compact package, will be prepared for this purpose. This didactic experiment will be presented with different degrees of details and conceptual background to audiences of various kinds, from visitors at the National Week for Science (fête de la Science) to pupils at school and high school, to students at University and Grandes Ecoles.
