Abstract

Ice cloud parameters have an important influence on global climate research and weather forecast. According to the atmospheric radiation theory, THz is the best frequency band for ice cloud remote sensing. In this paper, the principle and research status of ice cloud remote sensing is analyzed. The detection capabilities of different ice cloud sounders are compared, and a THz ice cloud imager for the next generation meteorological satellite is designed. The THz ice cloud imager covers five detection frequencies of 183GHz, 243GHz, 325GHz, 448GHz and 664GHz, and uses cone scanning mode, with the spatial resolution better than 10km, noise temperature better than 3000K.
