Thermal control design of a multi-channel scanning imagery radiometer

摘要

The multi channel scanning imagery radiometer is one of the main payloads of a geostationary earth orbit satellite , which can observe multi spectrum from the earth. The radiometer will endure complicated heat flux environment in orbit, and effective thermal design for the instrument is required in order to ensure high quality scanning image. Based on characteristics of the heat flux in geostationary earth orbit and the unique structure of the radiometer, thermal design characteristic was analyzed, and detailed thermal control design was developed based on numerical analysis. The numerical results verified the validity of thermal control design.
