在不同的型号任务中,对摆动扫描式红外地球敏感器在电磁干扰的环境中所达到的抗干扰能力需要进行考核。详细介绍了便携式摆动扫描式红外地球敏感器整机EMC试验专用性能测试设备的总体结构及主要部分结构设计,该设备能考核地球敏感器的整机性能指标,给出红外辐射信号,全面考核产品的光、机、电性能。所设计的地球模拟器针对卫星35 786 km和21 500 km两个轨道高度,采用可更换地球光阑的方案,提供17.46°和26.54°两种地球张角,所研究的测试设备实现了在地面上模拟卫星在太空中所看到的地球,供星上红外地敏在地面上测试性能使用。
In different types of tasks, the anti-interference ability of the wobble scanning infrared earth sensor in the environment of electromagnetic interference needs to be evaluated. This paper introduces the overall structure and the main part of the structure design of the portable oscillating scanning infrared earth sensor whole EMC test performance testing equipment. The device can test the performance indicators of the earth sensor, give the infrared radiation signal, the comprehensive evaluation of the product Light, machine, electrical performance. The designed earth simulator provides two kinds of earth angles of 17.46 ° and 26.54 ° for the orbital altitude of 35 786 km and 21 500 km for satellites. The earth aperture can be replaced by a replaceable earth stop, and the tested equipment has been tested on the ground The Earth seen in spacecraft on simulated satellites is used by the Earth for infrared geodetic testing on the ground.
