Dual-channel radiometers for Earth and atmosphere monitoring (DREAM) on micro satellite STSAT-2

The dual-channel radiometers for Earth and atmosphere monitoring (DREAM) is the main payload for the science and technology satellite-2 (STSAT-2) mission. This instrument is the first spaceborne microwave radiometer in Korea. It is a two-frequency, total power microwave radiometer with linear polarization. It operates at 23.8 GHz and 37 GHz for remote sensing of the Earth. In this paper, we present its system configuration and system design.
