The Tactical Synthetic Aperture Radar (TSAR) is a new radar system introduced on the MQ-8B Fire Scout unmanned aerial vehicle. It delivers high-resolution, wide-area radar images day or night, and in all weather conditions. TSAR systems take advantage of the long-range characteristics of radar signals and the information processing capability of modern digital electronics to provide high resolution imagery. The TSAR system can see through dense foliage, or penetrate sand and soil to image targets underground.
