摘要
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 model tasks,the antijamming ability of swing scanning infrared earth sensor in electromagnetic interference environment needs assessment.The structural design of overall structure and the main parts of portable swing scanning infrared earth sensor ′ s whole machine electromagnetic compatibility test dedicated performance testing were introduced in detail.This device is able to assess the performance of the whole earth sensor indicators,gives infrared radiation signal,comprehensive assessment on the optical,mechanical,electrical properties of products.The earth simulator in this paper adopts a project of replaceable earth diaphragm for two orbit heights 35 786 km and 21 500 km,and can afford two earth angles（17.46° and 26.54°）.In this paper,test equipment achieve simulating the earth of satellites in space have seen on the ground,for the satellite components infrared earth sensor testing performance on the ground.
