The Conically-Scanning Two-look Airborne Radiometer (C-STAR) is an airborne passive microwave radiometer developed at NASA's Marshall Space Flight Center (MSFC). It is a Ka-band (37 GHz) radiometer that measures ocean brightness temperature to determine precipitation rate and surface water and near-ocean-surface winds. It has a footprint size at nadir of 2 km x 3.5 km at a flight altitude of 10 km. C-STAR has an integration time of 100 ms and a scan rate of 6 revolutions per minute. It has a half-power beamwidth of 7.5 degrees and a field of view of 45 degrees.
