The Two-Dimensional Electronically Scanning Thinned-Array Radiometer (2D-STAR) is an airborne passive microwave radiometer that measures brightness temperature to determine surface soil moisture and ocean salinity. It operates in the L-band (1.413 GHz) and employs aperture synthesis in the along-track and across-track dimensions. At a nominal flight altitude of 7.7 km, 2D-STAR has a swath width of 10 km and a spatial resolution of about 800 m. It provides imagery every 0.2 seconds.
