　　先进微波大气探测仪（AMAS）是安装在风云三号卫星（C/D星）上的新一代微波湿度计，是风云三号卫星（A/B星）微波湿度计的继承和发展。在150 GHz（水平极化和垂直极化）和183.31 GHz（水平极化，三通道）的基础上，探测频率和通道设置为89 GHz（垂直极化）、118.75 GHz（水平极化，八通道）、150 GHz（垂直极化）、183.31 GHz（水平极化，五通道），仍采用垂直于飞行方向的交轨扫描方式，科学目标是探测全球大气温度和湿度的垂直分布、降雨等。本文介绍了微波湿度计-II的系统设计与构成，描述了微波湿度计-II的性能指标要求。测试结果表明，性能指标满足设计要求。

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.
