简要说明了形成电磁干扰的三要素和航天飞行器存在的电磁干扰问题。举例说明了电磁兼容分析方法和步骤,应用计算机作系统兼容性预测分析的原理和模型.介绍了航天飞行器的电磁环境要求,系统间和系统内电磁兼容设计技术。阐述了在单机经过 EMC 验收后为什么还要进行系统级试验的理由.提供了一个航天飞行器系统级 EMC 试验的试验配置,对测量系统各部分的功能和试验程序作了说明.
Briefly described the three elements of electromagnetic interference and the electromagnetic interference problems of spacecraft. An example is given to illustrate the principle and model of the electromagnetic compatibility analysis method and step, and the prediction and analysis of the compatibility of the system using the computer. The electromagnetic environment requirements of the spacecraft, the electromagnetic compatibility design technology between the systems and the system are introduced. The reasons for why the system-level test is still to be carried out after the stand-alone EMC test and acceptance are presented.A test configuration of the system-level EMC test of the spacecraft is provided, and the functions and test procedures of each part of the measuring system are described.
