Darpa seeks SAR for warfighter support

Advanced, flyable electronics and scene simulation technology sought for video synthetic aperture radar

Warfighters who encounter enemy forces on the ground benefit from overhead aircraft support. Some capabilities are lost, however, when cloud-cover obscures the view. Typically, airborne weapon systems that use electro-optic (EO) sensors during support missions can’t “see” through clouds. DARPA’s Video Synthetic Aperture Radar (ViSAR) program seeks to develop and demonstrate an Extremely High Frequency (EHF) targeting sensor which operates through clouds as effectively as today’s infrared (IR) sensors operate in clear weather.
