Description

The Department of Defense (DOD) is seeking proposals for the topic of "Passive Sensing for Distributed Radars" as part of their SBIR 24.1 BAA solicitation. The research aims to develop capabilities for passive sensing of distributed radars. The key technical objectives include passively collecting radar reflections, measuring the time difference of arrival (TDOA) of collected signals, determining the range of the object, calculating the location, heading, and speed of the object, developing techniques for accurate location, heading, and speed estimation with limited knowledge of the emitting source, and providing information for sizing passive arrays for different mission areas.

The typical sensors used in this research consist of a transmitter and a receiver, but passive sensors collect radar reflections using third-party transmitters in the environment. The proposed solutions could involve new passive sensing approaches, new processing algorithms, or a combination of both. The research will be conducted in three phases. In Phase I, radar reflections will be passively collected and the TDOA of collected signals will be measured. Phase II will focus on determining the bistatic range of the object and calculating its location, heading, and speed. In Phase III, the technology will be improved and a full design will be implemented, potentially including shrinking the system size, enhancing the hardware/software solution, and incorporating lessons learned from the previous phases.

The research falls under the Missile Defense Agency branch of the Department of Defense and is restricted under the International Traffic in Arms Regulation (ITAR) or the Export Administration Regulation (EAR). The project duration and funding specifics are not provided in the document. The solicitation notice can be found at the following link: SBIR Topic Link.

Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic of "Quantum Enhanced RF Components" as part of their SBIR 24.4 Annual solicitation. The objective of this research is to utilize quantum phenomenology to create sensitive Radio Frequency (RF) components that can enhance the performance of current communication systems. By lowering the noise levels of these components, weaker signals can be detected, potentially enabling the radar detection of previously unseen targets. The research will focus on developing quantum-based RF components such as amplifiers, mixers, and oscillators that can be integrated with existing systems. The project will be conducted in two phases. Phase I will involve delivering a series of reports outlining the feasibility of the RF component using mathematical models for quantum phenomena. Phase II will require the delivery of a working prototype and a report documenting the prototype's capabilities and any necessary control software. The potential applications of this technology include enhancing the efficacy of security systems that rely on RF detection, minimizing disruptions and identifying the source of RF interference in police and first responder communications systems, and improving communication and navigation capabilities in maritime and aviation vehicles. The project duration is not specified, but the solicitation is open until March 31, 2025. For more information and to submit proposals, interested parties can visit the DOD SBIR website.
DOD SBIR 24.4 Annual - Forward Looking Infrared (FLIR) Dual Band Focal Plane Array in High Definition Format
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of a small energy-efficient self-contained transceiver capable of wireless communication without using traditional radio frequency (RF) transport. The goal is to utilize a non-standard means of signal communication, such as magnetic, acoustic, or infrared, that is difficult to detect and report in covert activities. The transceiver should be highly resistant to interference, detection, and exploitation, and be self-contained, man-portable, easily concealable, and field programmable. The project duration is divided into two phases: Phase I involves creating a design and rationale supporting the solution, while Phase II focuses on developing and testing a prototype. The final product should be fully documented and include operating instructions, interface control documents, and programmability commands. The potential impacts of this technology include new mission deployment possibilities for remote sensor operation and control, as well as applications in areas such as home security, healthcare, additive manufacturing, and automotive safety. The deadline for proposal submission is March 31, 2025. For more information, visit the solicitation agency's website [here](https://www.defensesbirsttr.mil/SBIR-STTR/Opportunities/).

Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "Algorithms for Modular Remote Expendable Sensor Array" as part of their SBIR 24.4 Annual solicitation. The objective of this research is to develop and mature decision logic and signal processing approaches for modular, configurable, remotely deployable sensing capabilities for surveillance, targeting, or chemical hazard sensing. The technology will enable maneuver elements to have situational understanding of adversary actions and threat conditions in their areas of operation. The research will focus on the development of decision logic at the sensor node and sensor array fusion node to reduce raw data into actionable decision supportive information. The project will be conducted in three phases: Phase I involves developing a conceptual analytical approach, Phase II focuses on developing and demonstrating a prototype set of multi-modal algorithms, and Phase III involves refining and ruggedizing the system and integrating it into a representative Army network. The starting Technology Readiness Level (TRL) on completion of the SBIR Phase III execution period should be TRL6 or greater. The project duration is 24 months, and funding specifics can be found on the grants.gov website.

DOD SBIR 24.4 Annual - Low Cost Persistent Multi Sensor Surveillance

Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic of "Low Cost Persistent Multi Sensor Surveillance" as part of their SBIR program. The objective of this topic is to develop environmentally hardened sensor nodes that can persistently monitor Radio Frequency (RF), weather conditions, and/or personnel access of remote islands leased on the Kwajalein Atoll for the U.S. Army's Reagan Test Site (RTS). The solutions should be independent of external power sources or communications networks, as there are no cellular or Wi-Fi communications, nor power source, in these areas. The solutions must also be capable of operating in harsh environmental conditions, including heat, humidity, regular rainfall, salt spray, and high atmospheric salinity. The data collected by these sensor nodes will be used for situational awareness, safety, security, and mission planning and support. The solicitation is open for both full or partial solutions, and Phase I proposals with a cost of up to $250,000 for a 6-month period of performance are being accepted. Phase I will involve researching and developing the system/network architecture, designing the hardware components, and proposing power source designs and networking techniques. By the end of Phase I, the awardee should have detailed descriptions of the proposed technologies. In Phase II, the awardee will produce a single prototype that demonstrates the capabilities and methodologies at a minimum of TRL4. They will also develop a user interface and display for situational awareness of sensor control and monitoring. The potential applications of this technology include wireless remote sensing for public safety, health, fitness, and wildlife dual-usages. Some examples of dual uses of remote sensing include anti-poaching efforts, remote environmental sensors enabled by low-Earth orbit satellites, wildfire early recognition sensor systems, agriculture and crop performance monitoring, and urban pollution source detection.
