Soldier-Integrated Radar Detection and Location (1022-004-004)

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.
