-
摘要: Oceanic Multiband Microwave Radiometer（OMMR）是针对中国HY-2卫星扫描微波辐射计的定标和检验而设计的五频段十通道微波辐射计. 由于工作环境恶劣以及仪器长期稳定连续360°观测的需求，使其研制具有较大挑战. 本文重点介绍该微波辐射计的系统构成、技术指标设计与实现，阐述了系统指标测试和定标过程. 测试结果表明其满足设计要求.Abstract: Oceanic Multiband Microwave Radiometer (OMMR) with five frequencies and ten channels is designed for the calibration and validation of HY-2 satellite's scanning microwave radiometer. The development of this remote sensor is challenged with harsh working environment as well as long-term stable continuous 360° observation. In this paper, it is focused on the radiometer's system constitution, design and implementation of technical indicators. OMMR system includes eight functional units, i.e., antenna, receiver, scanner, calibration unit, temperature measurement, data sample and system control unit, power source and structure. The process of system indicators test and calibration is described. Testing results showed that the radiometer can meet the design requirements.
