The U.S. Army, through the Defense SBIR/STTR Innovation Portal (DSIP), invites proposals for its Small Business Innovation Research (SBIR) 2025.4 solicitation, specifically for the topic “Radar Signal Processing Improvements for Probability of Detection.” The initiative aims to support novel signal processing techniques that can improve the probability of detection for ground-based radar systems, especially at longer ranges, without compromising existing scan time requirements.
The solicitation seeks to address a critical gap in the Army’s radar capabilities. Existing systems face difficulty detecting long-range, surface-launched projectiles without adjustments that increase dwell time and compromise performance. Solutions must operate effectively in complex operational environments, including scenarios with electronic attack, multiple targets, and background clutter. The expected outcome is to identify techniques that enhance detection while remaining compatible with current radar hardware and timelines.
Eligible applicants are limited to small businesses under the SBIR program. Phase I proposals may request up to $250,000 for a six-month feasibility study that includes a test plan, real-world simulation, and implementation analysis using tools such as MATLAB. The study must demonstrate potential improvements through clearly defined metrics and propose integration strategies for field application.
Proposals must be submitted through the DSIP Portal, which supports the entire lifecycle of the SBIR/STTR process including solicitation access, topic browsing, and submission. Submissions for this topic open on January 29, 2025, and close on February 26, 2025. The broader DoD SBIR/STTR program follows a recurring twelve-cycle schedule, with this topic falling under Release 4. Applicants can consult DSIP resources such as templates, training materials, and topic Q&A forums during the pre-release period for support.
Phase II will focus on refining and maturing the algorithms from Phase I using high-fidelity radar models, targeting a minimum Technology Readiness Level (TRL) of 5. Successful technologies may be integrated into government System Integration Labs or Science and Technology (S&T) programs. Phase III envisions expanded commercial and defense applications, including automotive radar, weather tracking, public safety drone detection, and healthcare monitoring via radar-based vital sign detection.
For more information, applicants should refer to the DSIP portal or direct questions to the Army SBIR/STTR Help Desk at usarmy.sbirsttr@army.mil. No individual program officer is listed for direct contact.
Use simulation tools like MATLAB and present clear implementation metrics.
