Abstract
Advanced microwave atmospheric sounder(AMAS)is the new generation of microwave hu-midity sounder onboard FY-3(C/D)satellite,and is inheritance and development of MWHS onboard FY-3(A/B) satellite. Based on 150 GHz(horizontal and vertical polarization)and 183.31 GHz(horizontal polarization, three-channel)of MWHS,the AMAS still operated in cross-orbited scanning and used for deriving atmospheric temperature and humidity of the vertical distribution,rainfall,etc. The observation channels are advanced as 89 GHz(vertical polarization),118.75 GHz(horizontal polarization,eight-channel),150 GHz(vertical polariza-tion),183.31 GHz(horizontal polarization,five-channel).This paper mainly introduces the design and structure of AMAS and describes its performance requirements. Test results show that the performance indicators of AMAS meet the design requirements.关键词
