Radiometers
C-STAR
The Conically-Scanning Two-look Airborne Radiometer (C-STAR) is a passive microwave radiometer system on an airborne platform that collects data at 37.1 GHz. Making use of a rotating antenna, the C-STAR is able to produce images forward and aft of the aircraft ground track. Data is collected in both horizontal and vertical polarization for each of the forward and aft images. [Source: NASA]
