It is probable that the work under this effort will be classified under Phase II (see Description section for details).
PHASE III DUAL USE APPLICATIONS: Support the Government in transitioning the technology for Navy use. The Cognitive Maritime Imaging capability implementation will show a fully functional prototype that can be used in an operationally relevant environment in the Integrated Submarine Imaging System (ISIS) system (AN/BVY-1) through the Advanced Processor Build (APB) program.
A Cognitive Maritime Imaging capability should easily be applicable to both commercial and military imaging systems. Commercial systems for navigation, port security, surveillance, and surface military vessels can use this technology to improve image quality.

TITLE: Real-time Compression for Acoustic Array Time-Domain Data
|
TECHNOLOGY AREA(S): Battlespace, Electronics, Sensors
ACQUISITION PROGRAM: PMS 485, Maritime Surveillance Systems Program Office
The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and import of defense-related material and services, including export of sensitive technical data, or the Export Administration Regulation (EAR), 15 CFR Parts 730-774, which controls dual use items. Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with section 5.4.c.(8) of the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.
OBJECTIVE: Create innovative algorithms and software for commercial off-the-shelf (COTS) general-purpose computers and Digital Signal Processing (DSP) equipment capable of converting time-domain data from a passive acoustic array into a compressed data stream that can be transmitted via satellite communications (SATCOM) and rebuilt into a replica of the original data.
DESCRIPTION: The Navy is seeking solutions to enable data from acoustic arrays to be transmitted in real-time without degradation to shore facilities for processing by specialists. Such transmission solutions would reduce the need for installation of expensive data processing and display systems on ships and the requisite specially trained crewmembers on-board to perform real-time data analysis. Since the capability sought is expected to be fielded as software that can be integrated into the shipboard array processor system, the recurring cost to field the capability would be minimal.
Current surface Anti-Submarine Warfare (ASW) practice for Surveillance Towed Array Sensor System (SURTASS) ships requires installation of an expensive, custom-built data processing system on each ASW ship, because the data from the arrays is too large to be transmitted to shore in real-time via Navy satellite communications (SATCOM). The quantity of data expected to be created by next-generation arrays is even greater and available satellite data bandwidth is not expected to grow from its present size. Therefore, current and future ASW platforms need a lossless data compression capability that enables raw time-domain data from each element of the array (up to 256 channels simultaneously) to be transmitted to shore and reconstructed as an exact replica to enable accurate data processing and precise target localization.
A unique solution to acoustic data compression is required for this application. Unlike consumer audio applications in which psychoacoustic phenomena are leveraged and much of the inaudible data is selectively removed, the compression scheme must preserve the time-domain waveform precisely in both amplitude and time across all sensor channels in order for the array beamforming performance to be fully exploited by the DSP system. Additionally, unlike commercial audio applications, all sensor channels are receiving data from a common real-world physical source (e.g., there is not a guitar on one channel and a vocal on another); therefore, each channel is processing the same acoustic data, but with variations in amplitude and time among the channels. It may be assumed that the configuration of the sensors, including their spacing and bandwidth, is provided to the compression and decompression algorithm. Sampling rates may vary among sensor channels. It should be noted that ambient noise needs to be preserved in the compression, and electronically induced sensor noise can be assumed less than ambient noise (and therefore inconsequential).
The product for this effort is software source code that can be integrated into the Navy’s common processor system, which is based upon the Intel x86-64 platform and the Linux operating system. (Previously other SBIR-sponsored software projects have been integrated into this common processor system, and appropriate safeguards to protect the contributors’ intellectual property have been put in place.) A COTS DSP device may be used if required, but it will need to be integrated into the processor system. It is acceptable to leverage available open-source code. The objective ratio of compression is 80% compared to the raw array data stream with an input/output latency of less than one minute.
In summary, the capability includes the following characteristics that are not available in today’s lossless compression/de-coding schemes:
1. Input has user-variable number of channels up to 256
2. Output incorporates forward error correction (FEC) with automatic negotiation capable of supporting radio/satellite data links with a bit error rate of 0.01, end-to-end latency of two seconds, and data block outages of up to two seconds
3. Including FEC, output is single data stream composed of 80% of the data volume compared to raw data
4. Sample rates can be selected by the user in 1Hz intervals up to at least 96kHz
5. Sample rates can vary among channels, but will be in integer multiples of each other
6. After coding and de-coding, the time domain waveform shall be visually identical to the original with objective performance of true effective 16-bit resolution (96dB dynamic range), < 0.05% Total Harmonic Distortion (THD), frequency response accuracy +/- 0.1dB, and phase accuracy between channels of +/- 1 degree at 0.9*(Nyquist frequency/2)
7. Coding and de-coding processing latency not to exceed one minute
Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. Owned and Operated with no Foreign Influence as defined by DOD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Security Service (DSS). The selected contractor and/or subcontractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this contract as set forth by DSS and NAVSEA in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advance phases of this contract.
PHASE I: Develop a concept for real-time lossless compression for acoustic array time-domain data implementation and perform analysis, modeling, and/or a demonstration to support the technical recommendation. The Phase I Option, if awarded, will include the initial design specifications and capabilities description to build a prototype solution in Phase II. Develop a Phase II plan.
PHASE II: Using the requirements and concept of Phase I and the Phase II Statement of Work (SOW), develop and deliver a prototype for a complete implementation of the data compression and decoding capability. Demonstrate the prototype’s performance in a lab using real-life array data that will be supplied by the Navy. (Since this data is classified, this demonstration can be performed on accredited classified equipment in the performer’s facility or at a Navy facility.) Support a temporary installation of the compression capability aboard a Navy ship to demonstrate the performance of its design in an operational environment; support the installation of the decoding capability at a Navy shore site; and provide operational testing technical support and performance analysis. In preparation for a potential Phase III, provide an estimate of schedule, non-recurring cost, and product cost to support integration of the capability into the Navy processor system.
It is probable that the work under this effort will be classified under Phase II (see Description section for details).
PHASE III DUAL USE APPLICATIONS: Support the Navy in transitioning the technology to Navy use. Work with the Navy’s integrator to support the integration and testing of the capability into the Navy processing equipment on-board an operational SURTASS ship. Tasks may include software development, software quality assurance, cybersecurity support, development of documentation, and test support on shore and at-sea. Deliver future software/hardware builds of the processor system with the SBIR-developed integrated compression and de-coding capability.
Passive acoustic arrays are used in the oil industry and this data compression capability would have direct application for data storage or transmission via radio. As an example of a business case, this data compression capability could be used to decrease deployment costs significantly by enabling the use of a relatively inexpensive unmanned vessel to collect acoustic data rather than a ship with crew ($50k-100k/day).

TITLE: Pattern Recognition Algorithms for Detection of Latent Errors in Combat System Software
|
TECHNOLOGY AREA(S): Battlespace, Electronics, Sensors
ACQUISITION PROGRAM: Program Executive Office Integrated Warfare System (PEO IWS) 1.0 – AEGIS Combat System
The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and import of defense-related material and services, including export of sensitive technical data, or the Export Administration Regulation (EAR), 15 CFR Parts 730-774, which controls dual use items.

Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.
OBJECTIVE: Develop pattern recognition algorithms that identify and characterize latent errors in the software code of the AEGIS operational software prior to deployment.
DESCRIPTION: The software for the AEGIS system is a critical component of ship and strike group self-defense. Therefore, software quality is of utmost importance. Any software defects (bugs) present in the AEGIS software can have mission-critical impacts on the defense of the Navy’s Fleet assets. In order to field the best software to the Fleet, AEGIS software must undergo thorough testing. Throughout the software development process, AEGIS undergoes hours of testing, producing terabytes of data. The testing is accomplished with two AEGIS labs and a modeling and simulation suite concurrently providing Combat System data. The current process of debugging includes the following steps: find the bug through testing, conduct additional testing to determine the bug’s priority (mission criticality and impact) and probability (chance of occurrence), root cause the bug to specific code areas, and fix the bug. After this process is completed, it is repeated to ensure elimination of the bug and determine if there are any changes that might create another bug. These processes are necessary because a missed bug that is fielded may degrade a ship’s combat capability or create an unintended loss of life or dangerous operational situations. While the commercial industry has the ability to field less than perfect software and simply respond to user complaints on functionality through rapidly deployable upgrades, military software such as AEGIS must have a much higher fidelity in functionality to avoid unintended impacts on human life.
Similar to current commercial debugging processes, the current AEGIS testing process provides terabytes of data that can lead to possible issues, but AEGIS data is not currently analyzed unless there is a visible error onboard the ship. Unfortunately, the manual analysis by humans of all of the AEGIS data generated through testing is not cost-effective, which drives the need for machine-learning algorithms to learn system behavior and identify out-of-pattern behaviors. Additionally, unlike commercial software upgrades, AEGIS upgrades go through longer approval and certification timelines before they can be released. Subsequently, reducing these timelines through automated data analysis can significantly impact both cost and performance of the AEGIS Combat System (ACS).
The Navy seeks a technology that provides the capability to automatically find and characterize bugs. This automation capability will analyze recorded data from AEGIS to find latent errors and provide data-driven priority and probability prior to AEGIS certification and deployment. This technology will enable high priority bug detection and repairs before fielding the system and enable the fielding of a combat system at full capability. As a result, development and maintenance costs of the AEGIS software will be reduced. Latent error detection will ensure that the best quality software is fielded to the Warfighter and works every time. Testing can be very expensive; therefore, the better the Navy becomes at finding and fixing software bugs, the less testing will be required. This will result in a more capable upgrade, faster deployment, and cost savings.
The software solution will analyze 300 terabytes of AEGIS data throughout the development lifecycle of a baseline. In doing so, the software solution will use big data and machine learning algorithms and technology to characterize the patterns of AEGIS system behavior and identify out-of-process behaviors that lead to system failure. Through analysis of large amounts of AEGIS data, the software solution will provide large-scale analysis of AEGIS software data that encompasses all testing for the baseline. This will help AEGIS find and fix high priority bugs via (1) finding bugs that have been overlooked by systems analysts and (2) providing better data on the probabilities and impacts of bugs. This will be measured by identifying the number of defects found by the technology and comparing that number to the number of defects found by the Government analyst team through traditional methods. The goal is for the software solution to increase the number of high-priority bugs found by a minimum of 10%. The software solution must also be able to identify whether defects have been fixed over the lifetime of the AEGIS software development, and are no longer issues in the most recent builds.
The Phase II effort will likely require secure access, and NAVSEA will process the DD254 to support the contractor for personnel and facility certification for secure access. The Phase I effort will not require access to classified information. If need be, data of the same level of complexity as secured data will be provided to support Phase I work. Phase II and Phase III will include work with the AEGIS Prime contractor, Lockheed Martin.
Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. Owned and Operated with no Foreign Influence as defined by DOD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Security Service (DSS). The selected contractor and/or subcontractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this contract as set forth by DSS and NAVSEA in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advance phases of this contract.
PHASE I: Develop a concept for pattern recognition algorithms that automatically reveal bugs in software. Determine feasibility through modeling and analysis of data sets and show it meets the requirements as described in the description. The concept will show it can feasibly analyze outputs of AEGIS software data extraction and find latent errors that may contribute to mission failure. The AEGIS Program Office will provide sample unclassified data for the topic. The Phase I Option, if awarded, will include the initial design specifications and capabilities description to build a prototype in Phase II. Develop a Phase II plan.
PHASE II: Based upon the results of Phase I and the Phase II Statement of Work (SOW), design, develop, and deliver a prototype for pattern recognition algorithms that automatically finds and characterizes bugs in software. The prototype will provide analysis tools that will work with AEGIS software and demonstrate it effectively finds latent software errors and characterizes the priority and probability of those errors. The demonstration will take place at a Government- or company-provided facility. The company will prepare a Phase III development plan to transition the technology for Navy production and potential commercial use.
It is probable that the work under this effort will be classified under Phase II (see Description section for details).
PHASE III DUAL USE APPLICATIONS: Support PEO IWS 1.0 in transitioning the technology for Navy use to allow for further development, refinement, and testing. The implementation will be a fully functional software tool that provides continuous analysis of test data to ensure AEGIS works the first time and every time. Integration will be through the development cycle for AEGIS at Lockheed Martin and Government test facilities.
Any software development company, including Apple, Microsoft, Google, etc., has software bugs. These companies look to improve their software development process to drive down costs and create software in the cheapest and most effective ways possible. Similar to AEGIS, these companies all track their bugs, and have comprehensive test plans that work through system capability to define bugs. Therefore, there is significant commercial application for the technology detailed in this topic.

OBJECTIVE: Develop a compact, modular, galvanically isolated, Direct Current (DC) distribution Integrated Power Node Center (IPNC) to supply mission-critical equipment with high-quality, uninterruptible power.
DESCRIPTION: Future Navy ships will include mission critical equipment with DC interfaces in addition to traditional 60Hz and 400Hz systems. Development of this compact DC power distribution Integrated Power Node Center (IPNC) will avoid costly, custom solutions needed to address each particular load.
IPNCs are being employed for replacing existing 400Hz Alternating Current (AC) power systems onboard U.S. Navy amphibious ships and destroyers, which currently use centralized and redundant frequency conversion.
Currently the 400Hz power (defined by MIL-STD-1399) is generated in centralized locations and then distributed via a combination of load centers, cabling, Automatic Bus Transfers (ABTs), transformers, and power panels to numerous loads located throughout the ship. This traditional distribution system approach leads to the placement of large and expensive frequency converters at strategic locations onboard the ship and significant distribution components, requiring long cable runs. A more effective and survivable approach would utilize the existing 60Hz distribution system to provide power to compact IPNCs located directly at the load site.
