TSC proposes an SAA radar system for the RQ-7 UAS by re-purposing an existing small, low-cost, multi-channel pulse-Doppler radar. This highly flexible system, when combined with a high power amplifier and a novel multi-faceted antenna concept will provide the Army with a low-risk path to an Airborne SAA system for the RQ-7 or similar UAS . The proposed system can operate day or night, in rain or fog, and will provide 360 degree non-cooperative detection and tracking of targets single-engine Cessna size and larger out to 3 nmi.
