Abstract

RAL Space has delivered four engineering qualification model (EQM) front-end receivers (FERXs) for the Microwave Sounder (MWS) and Microwave Imager (MWI) on-board the MetOp Second Generation (MetOp-SG) satellites. This mission will provide the European and wider global communities with weather forecasting services from 2022 to 2043. The two EQM FERXs developed by RAL for the MWS operate in the 183 and 229 GHz frequency ranges, featuring average double sideband (DSB) noise figures (NFs) of 5.3 and 6.2 dB, respectively. This paper presents the design and main characterisation results of these two state-of-the-art FERXs for the MWS and compares their performance with other in-orbit microwave sounding instruments, including those on-board MetOp.

MetOp-SG上用于微波测深仪的183 GHz和229 GHz EQM前端接收机

RAL空间公司为MetOp第二代卫星(MetOp- sg)上的微波测深仪(MWS)和微波成像仪(MWI)提供了四个工程鉴定模型(EQM)前端接收器(FERXs)。该任务将为欧洲和更广泛的全球社区提供2022年至2043年的天气预报服务。由RAL为MWS开发的两个EQM ferx工作在183 GHz和229 GHz频率范围内，其平均双边带(DSB)噪声系数(NFs)分别为5.3和6.2 dB。本文介绍了用于MWS的这两种最先进的ferx的设计和主要特性结果，并将它们的性能与包括MetOp在内的其他在轨微波探测仪器进行了比较。
