风云三号C星微波大气探测载荷性能分析
The Performance of Microwave Sounders Board on FY-3C Satellite
中文摘要：
风云三号C星是我国第二代极轨气象卫星的首发业务星，星上装载了3个被动微波遥感载荷（微波成像仪、微波温度计Ⅱ型和微波湿温探测仪），其中微波成像仪完全延续了风云三号A/B星的设计，两个微波大气探测载荷微波温度计
Ⅱ型和微波湿温探测仪是在风云三号A/B星微波温度计和微波湿度计成功在轨运行和应用的基础上，根据应用需求在功能和性能两个方面从设计层面实现了大幅提升。本文重点介绍风云三号C星微波温度计Ⅱ型和微波湿温探测仪的功能、
性能和设计指标，综述风云三号C星星载微波大气探测能力。风云三号C星星载微波大气探测系统，通过通道细分、探测频点增加和空间采样技术优化，突破了我国星载微波探测载荷技术瓶颈，提升了大气温湿度廓线的综合探测能力。

Abstract：
FY-3C is the first satellite of Chinese second generation operational polar orbiting meteorological satellite series. Three passive microwave instruments are on board the FY-3C satellite: MWRI is just following the design of FY-3A/B, MWTS-Ⅱ has
made great progress on channels splitting at the oxygen absorbing lines, and MWHTS has not only made more channels at vapor absorbing line, but also designed a new sounding frequency at 118GHz. All those have made great progress at the design stage.
In this paper, we give some key points on FY-3C/MWTS-Ⅱ and MWHTS, introduce the performance and design parameters of them. And finally we make an analysis on retrieval and sounding.
