KEYWORDS: satellite communications, SATCOM, networking, IP routing A03-115 TITLE: Small, Bandwidth Efficient Satellite Communications Modems and Waveforms TECHNOLOGY AREAS: Information Systems ACQUISITION PROGRAM: PM WARFIGHTER INFORMATION NETWORK-TACTICAL (WIN-T) OBJECTIVE: Design and build a small, bandwidth efficient satellite communications modem suitable for use with small aperture antennas in moving vehicles where communications is not the primary mission of the vehicle. DESCRIPTION: Satellite communications while on the move (SOTM) is a very important requirement for the Army’s Future Combat Systems/Objective Force. This capability allows warfighters to disperse to any location on the battlefield without being constrained by the limited ranges of terrestrial communications. The size, weight, and power limitations of battlefield vehicles mandate that SOTM antennas be small (generally around 16 inches in diameter). Networks comprised of many SOTM terminals do not manage satellite resources (i.e. power and bandwidth) in an efficient manner. Satellites have a limited power budget that must support all of the communication links utilizing the available bandwidth. As the satellite terminal antenna aperture decreases, the power per bit necessary to close the downlink from the satellite increases considerably. As a result, it is not uncommon for small SOTM terminals to require orders of magnitude more power than larger SATCOM terminals utilizing the same amount of bandwith. The Future Combat Systems and Objective Force systems architectures require a large number of small, on the move, SATCOM terminals. These networks will consume a large portion of the satellite’s power budget to utilize a small percentage of the available bandwith. This is an inefficient use of very important, and very expensive, satellite communications resources. Satellite power budgets will not be able to execute these architectures unless significant increases in power efficiency and bandwidth allocation are realized. New modem and waveform technologies are needed to increase data rates and bandwidth utilization without increasing the power requirements. Cross polarization and channel sharing schemes like demand assigned multiple access (DAMA) are examples of traditional methods that need further study and refinement, while new methods may need to be developed. In addition, power efficient waveforms with low signal to noise ratio carrier acquisition are needed for on-the-move operations with small antennas. PHASE I: Develop overall system design that includes specification of the modem, waveform(s) and satellite access protocols and how these will lead to efficient utilization of satellite resources by networks of small terminals. PHASE II: Develop and demonstrate a prototype modem in a realistic environment. Conduct testing to prove feasibility over extended operating conditions and ability to support networks of numerous small terminals. PHASE III DUAL USE APPLICATIONS: This system could be used in a broad range of military and civilian communications applications where there is a need for on-the-move satellite communications – for example, in overseas peacekeeping operations, emergency response/disaster relief operations, mobile news coverage, and in-vehicle business communications and entertainment systems.

A03-116 TITLE: Satellite Access Using Unmanned Aerial Vehicles TECHNOLOGY AREAS: Information Systems ACQUISITION PROGRAM: PM WARFIGHTER INFORMATION NETWORK-TACTICAL OBJECTIVE: Design and build an airborne satellite communications payload capable of operating in an unmanned aerial vehicle and interfacing with a separate terrestrial communications relay payload while sending communications and network traffic over the appropriate link based on policy inputs. DESCRIPTION: The Future Combat Systems (FCS)/Objective Force (OF) communications architecture places a high reliance on unmanned aerial vehicles (UAVs) as "relays in the sky". Part of this function includes UAVs serving as entry points to provide satellite communications capability to terrestrial radio networks without requiring satellite terminals on the ground. It is challenging to design a small satellite communications (SATCOM) terminal and antenna that can fit in the size, weight and power requirements for planned Army UAVs and maintain a continuous SATCOM link while in flight. This includes tradeoff between UAV payload and range capability and the terminal and antenna size and supported satellite communications data rate, to satisfy the requirements of the FCS/OF communications architecture. Another challenge is to provide a robust and dynamic networking capability that will enable effective use of this satellite communications capability by sending traffic over the most appropriate link (from the UAV to the ground, another UAV, or satellite) based on connectivity to the destination, traffic priority and amount of traffic. Various aspects of this technology have been demonstrated in current commercial and military efforts in migrating to Ka-band satellite communications using small, portable and on-the-move terminals and in mobile, ad hoc networking. Also, UAVs payloads are already under development to provide communications relays between terrestrial users. The challenge is to apply and integrate these technologies and concepts to extend the developing two-dimensional network (terrestrial and UAV) to a third (space) dimension while making the most effective use of the limited UAV payload space and UAV relay and satellite communications bandwidth. Without this capability, terrestrial users will require multiple radio and antenna assets for full-spectrum connectivity, or they will not have access to effective, continuous communications under all circumstances. The number of SATCOM terminals required for connectivity will be much greater, as will the cost to purchase the number of terminals required to support the FCS/OF communications architecture. PHASE I: Develop overall system design that includes specification of UAV satellite communications payload, interface(s) to UAV communications relay payload, and smart networking algorithms/protocols. Deliverables for Phase I should include a System Design Report and a Protocol Design Document. PHASE II: Develop and demonstrate a prototype system in a realistic environment. Conduct testing to prove feasibility over extended operating conditions. PHASE III DUAL USE APPLICATIONS: This system could be used in a broad range of military and civilian communications applications where there is a need to reduce the number of terminals per user while maintaining robust wide-area connectivity with minimal to no terrestrial infrastructure – for example, in overseas peacekeeping operations or emergency response/disaster relief operations. Commercial sectors are proposing many systems for air craft comms support in areas of large population to include manned/unmanned/blimbs to augment comms requirements.

A03-117 TITLE: Disposable Micro-Radios for Sensor and Munitions Networks TECHNOLOGY AREAS: Information Systems ACQUISITION PROGRAM: PM RUS APM OBJECTIVE: To research, design, and prototype a disposable micro-radio for sensor and munitions networks. The radio must incorporate RF waveform security (LPI, LPD, & AJ) required of military radios and be able to survive in a military environment through the use of adaptive ad-hoc networking protocols. Although the Networked Sensors for the Objective Force (NSOF) is currently developing radios, known as the "Blue" and "Orange" radios, for the ATD, the need for a smaller and less expensive radio exists. This radio will satisfy the need for communications for the unmanned sensor and munition systems that will be deployed in a disposable manner. A disposable radio, with RF waveform security, will also have a strong aplicability in both Homeland Security and commercial applications. DESCRIPTION: The US Army’s Future Combat Systems (FCS) and Objective Force Warrior (OFW) will rely on the use of unattended, tactical sensors to detect and identify enemy targets in order to survive on the future battlefield with less armor protection. Successful implementation of these critical sensor fields requires the development of low cost sensors, processors and the specialized communications infrastructure needed to disseminate the sensor data to provide relevant situational awareness information. The sensor communications must support both static deployed and mobile ground and air robotic sensor arrays with robust, secure, stealthy, and jam resistant links. It is envisioned that sensor networks can be deployed in a two tiered communications architecture that includes a lower sensor sub-layer consisting of acoustic, magnetic, Chem/Bio and/or seismic detectors and an upper sub-layer consisting of infrared or visual imaging cameras. The upper sub-layer can be cued by the lower sub-layer and provides a seamless gateway link to higher echelon tactical networks such as the Tactical Internet. The NSOF Advanced Technology Demonstration (ATD) communications effort will also focus on providing Objective Force systems such as FCS, Objective Force Warrior with the critical situational awareness data needed for survivability. The communications systems supporting this functionality must be designed such that unattended ground sensor data can flow seamlessly from the lowest unattended tactical sensor echelons into the Army’s Next Generation Tactical Internet while also allowing the “fusing” of the data with other intelligence information for correlation within a tactical command and control node. NSOF will realize this capability using advanced communications technologies that were previously unavailable. These technologies include robust, self-organizing networking protocols, energy management techniques, and stealthy, secure, jam resistant radio equipment for a significantly enhanced communications capability. Applications such as Objective Force Warrior will also require the sensor networks to be miniaturized, disposable and low cost. Soldier portable sensor networks will be carried by dismounted soldiers as buildings are cleared in urban areas. The sensors will continuously monitor the urban areas as the soldiers continue their missions providing alerts as needed. Miniaturization of key components and power considerations will need to be examined. New manufacturing techniques have been emerging to allow radio frequency components and sub-systems in ultra-miniaturized packaging that can be cost effective in sufficient quantities. These advanced packaging technologies will be critical in achieving the requirements. This innovation using sensor network technologies will benefit the Army transformation. Project Manager, Robotics and Unmanned Sensors (PM RUS) under the PEO IEWS organization supports the concept of networked communications for its sensor systems. PM RUS would be the organization to put the sensor networks in the field. The Joint Program Office Joint Tactical Radio System (JPO JTRS) would oversee the communications acquisition to ensure JTRS compliance of the developed waveform for joint use on any JTRS compliant platform. Every effort will be made to ensure the commercial off the shelf market is leveraged for the networked communications. There is also a growing market for sensor networking applications for remote monitoring of sites such as utility pipelines and factories that could reduce the unit costs of the communications devices. However, military security requirements such as low probability of detection, privacy, authentication and information assurance will be maintained. For Dual Use applications, these features may be turned off when not needed. The features also could be used for Homeland Security Counter-Terrorism applications when security is needed but not to the level required by the tactical military. HLS applications will increasingly rely on miniaturized disposable sensor networks for perimeter and infrastructure defense as the threat continues. PHASE I: Research and develop a design for a disposable micro-radio for military and homeland security sensor and munition networks. The radio design and architecture shall be minimal in power, cost, size, and weight. The radio design shall include the operating and routing software design needed to form an low-power and power-aware ad-hoc sensor/munition network. The radio's waveform design shall include securities in the form of low probability of interception, low probability of detection, anti-jam, and data encryption. The radios operating frequencies shall be consistent with the more efficient frequency ranges found with the current near ground propagation models. The radio design shall include a link-budget analysis showing that the radios are capable of providing RF communications over distances of at least 100 meters in both urban and rural terrains. Use of existing components or radios designs in novel ways is encouraged. If a existing design is to be used, a descriptive plan must be included documenting how the design will be modified to include the waveform securities and ad-hoc radio software, if needed, while minimized the power, cost, size, and weight of the radio. PHASE II: Prototype and integrate the radio design and ad-hoc radio software that was approved in Phase I. If a modified radio hardware design is used, the related radio software and networking software shall be updated to reflect the changes in radio design. A demonstration of a sensor network consisting of 50 to 100 prototype radios developed in Phase II shall be given in a realistic homeland security application. PHASE III: The radio hardware and software that was developed and prototyped in Phase I and II shall be transitioned to both military and commercial sectors. In the military sector, the radio hardware and software could help fill the void in the Networked Sensors for the Objective Force ATD for an inexpensive and disposable radio for sensor and munitions networks. This radio would be used to form sensor networks in areas where lower-precision, as compared to the ATD, sensors are used. They may also be used to awaken the more powerful NSOF ATD sensor nodes allowing the ATD sensors to remain in a more power-efficient sleep state. In the commercial sector, the developed radio will increase the capabilities of Homeland Security sensor networks. A possible use of this radio in a homeland security application is a quickly and inexpensively deployed perimeter control system used by local or State authorities. The developed radio will also be applicable in industrial applications where there is a need for a inexpensive but secure radio network. A possible application in the industrial world would be for monitoring the soil conditions (acidity, moisture, etc.) found at the larger farms.

A03-118 TITLE: Digital Dynamic Pre-Distorter for High Power Amplifiers for Wideband Digital Radios TECHNOLOGY AREAS: Electronics ACQUISITION PROGRAM: PM TRCS OBJECTIVE: Develop a digital pre-distorter for RF waveforms in the 2-2000 MHz range to linearize the frequency response of multi-carrier high power amplifiers over bandwidths of 100 MHz or more. High dc-to-rf efficiency and low intermodulation distortion are required. This technology would be applicable to all RF transmitters, especially to the JTRS communication system as well as any communication system for Homeland Security. DESCRIPTION: In an RF transmit system, a low power exciter signal is amplified by a chain of amplifiers culminating in a high power amplifier (HPA). In modern wideband multi-carrier communication applications, such as the JTRS radio, the cumulative transfer function of entire amplifier chain must be linear over this wide frequency band. The conventional approach of combining the RF outputs of individual single-carrier narrowband HPAs to reduce intermodulation distortion wastes too much power and is too expensive. Typical wideband amplifiers inevitably exhibit a trade-off between high power-efficiency and nonlinear distortion. The more efficient wideband amplifiers can only be used if the input signal to these devices is predistorted to compensate for the amplifier nonlinearity. HPA linearization techniques using digital pre-distorters at baseband are available but are limited in bandwidth and are not fast enough to correct for dynamic signal-induced nonlinearities. Dynamic (real-time) digital pre-distortion at RF frequencies provides a way to increase bandwidth, DC-to-RF efficiency, and reduce cost, and size of high-power transmit amplifiers, more effectively than at baseband. Solutions are needed for real-time adaptive digital pre-distorter circuits for bandwidths of 100 MHz or greater in the 2-2000 MHz frequency range. Compatibility with ultra-fast digital-to-analog converter technology for direct digital synthesis of RF waveforms is required. PHASE I: Demonstrate the proof-of-principle of the digital predistorter circuit architecture through simulation and experimentally verify the operation of circuit components. PHASE II: Build and demonstrate a complete digital pre-distorter circuit. PHASE III: Military Application: The wideband real-time digital predistorter technology could be inserted into future JTRS radio family members as a pre-planned product improvement. This technology could also be directly applicable to any communication system for Homeland Security. Commercial Application: The wideband real-time digital predistorters will find widespread use in commercial wireless communications, especially the third generation (3G) and beyond, where cost savings for multi-carrier base stations would be significant.

A03-119 TITLE: PAMELA: Propagation Analysis and Modeling Experiments for Laser Applications TECHNOLOGY AREAS: Electronics ACQUISITION PROGRAM: PM AJCN OBJECTIVE: Laser communication has undergone significant investigation on its critical impact to the Transformation Communication Study (TCS) at the Pentagon. Several programs throughout DoD have been ongoing to address issues of technology. However, there has been limited resources to address the modelling of the laser link with respect to atmospheric turbulence. Very little has been done to integrate laser propagation parameters with turbulence metrics to predict limits on tactical performance and applications. Its is of dire need to undertake this type of analysis to predict tactical feasibility of laser communication for ground/airborne/space applications. Free-space laser communication and active laser imaging are emerging technologies that share a number of common challenges. Both of these technologies involve the focusing and transmission of laser energy through the atmosphere and share problems related to signal reception, tracking, pointing, laser speckle, and information processing. With the advent of emphasis on space based military network, it is critical to have a complete model to determine practical constraints of military use. Modeling of this nature is extremely important for the deployment of fielded military systems. The objectives of this research are to: · Propose a novel integration of atmospheric effects with mitigation and data communication coding techniques · Validate experimentally the transmission of information using novel types of sources · Investigate aspects of polarization and partial coherence · Incorporate model in a network DESCRIPTION: Laser communication could have a key role in three significant areas in high bandwidth communication systems: terrestrial to terrestrial, satellite to terrestrial, space craft to satellite, or a variation of all three. On the terrestrial side, wireline network have been preferred, but recent advances have made free space optical communication advantageous for a variety of applications including those involved in which ground installation may be prohibitively costly. For military applications, covert laser communication is harder to intercept than RF systems because of its smaller angle of acceptance. In satellite systems, such as Teledesic, cross-link pipelines are needed to transmit gigabits of information to interconnect globally. Network manager may be required to downlink data directly from LEO satellites or send data from an on-the-move vehicle. PHASE I: Develop a theoretical model basis. Model should be convincing and made generic to a wide range of applications and implementations of laser communication. Framework of the model should include key system performance criteria of a data communication system and include atmospheric propagation parameters that have effect on these metrics.
