SBIR-STTR Award

SI2 Technologies, Inc. (SI2) proposes to build a radar detector and locator system integrated with the existing warfighter uniform to increase soldier lethality by enabling undetected maneuvering in the presence of hostile radar surveillance. This system alerts to the presence and direction of Ground Surveillance Radar (GSR) or Battlefield Surveillance Radar (BSR) at distances beyond maximum radar detection ranges, while fusion of data from multiple personnel reduces shadowing from structures and generates finer resolution for the radar location to enable further action against threat radar sites. During Phase I, SI2 will build on prior flexible antenna system experience to design and fabricate antennas and electronics that are compatible with integration into the battle uniform of the soldier. We will also update the Angle of Arrival (AoA) algorithms to operate with the antenna topology developed. SI2 will test the antennas and electronics to demonstrate compatibility with mounting within the soldier’s uniform while meeting the system requirements to detect, identify, and locate the hostile radar signal. SI2’s innovative solution will provide the US Army, other DoD sectors, and interested parties, with a system to detect, classify, and locate GSR and BSR installations before the radars can detect the soldiers.

SI2 Technologies, Inc.(SI2) and the New Jersey Institute of Technology (NJIT) propose to build on their successful Phase I prototype radar detector and locator system, manufacturing a radar detector system that can be integrated with the existing warfighter uniform to increase soldier lethality by enabling undetected maneuvering in the presence of hostile radar surveillance. The system alerts to the presence and direction of Ground Surveillance Radar or Battlefield Surveillance Radar at distances beyond maximum radar detection ranges. SI2’s proposed radar detector and locator system is low power, lightweight, and conforms to the soldier’s uniform, providing a solution that alerts the warfighter of enemy radar prior to entering the weapons engagement zone without adding to the extensive equipment the soldier already carries. SI2’s solution includes a four-element sparse array and low-power commercial, off-the-shelf electronics integrated on a conformal surface and the utilization of partner NJIT’s angle-of-arrival algorithms to detect radar signals beyond the tracking range. Using this technology with multiple individual fighters can calculate an accurate location of the radar detector as well, providing soldiers with a detector and locator long before the radar detector locates the warfighter.
