Korean spaceborne microwave radiometer on STSAT-2: Dual-channel Radiometers for Earth and Atmosphere Monitoring (DREAM)

Dual-channel Radiometers for Earth and Atmosphere Monitoring (DREAM) is the Korean first spaceborne radiometer which is the main payload of Science and Technology SATellite-2 (STSAT-2). The satellite will be launched by Korea Space Launch Vehicle-1 (KSLV-1) at NARO Space Center in Korea in 2007. DREAM is a two-frequency, total power microwave radiometer with linear polarization. It measures the brightness temperature of the Earth at 23.8 and 37 GHz. In this paper, the characteristics and the preliminary design of DREAM are described.
