DARPA’s Video Synthetic Aperture Radar (ViSAR) program recently completed flight tests, successfully demonstrating a new sensor that can capture real-time video through clouds.
Cloudy skies, dust and other vision-obscuring conditions often limit the support capabilities overhead aircraft can provide warfighters on the ground. Airborne weapon systems that use electro-optic and infrared (EO/IR) sensors during support missions can’t “see” through clouds, and current synthetic aperture radar (SAR) technology can’t provide high-resolution video imagery of moving ground targets through clouds.
