飞行器外部电磁环境分析与辐射安全裕度试验方法研究

辐射安全裕度是系统级电磁兼容性的关键指标,是保证系统能够在使用环境下正常工作的前提。从安全裕度的定义出发,分析外部电磁环境对于系统安全裕度的重要意义,指出现有辐射安全裕度试验方法的缺陷。提出用于评估外部电磁环境的两种方法,并指出考虑外部电磁环境后辐射安全裕度测试的难点。文中还分析了系统对外部电磁环境的感应特性,提出一种新的辐射安全裕度测试方法,降低了测试难度,使安全裕度测试更加全面、有效。

Analysis of the EME of the Airplane and Study of the Radiation Safety Margin Test

The radiation safety margin is the key indication of system-level electromagnetic compatibility requirement,and also is the precondition to ensure that the system can work smoothly in the environment.Beginning with the definition of the safety margin,this paper analyzes the significance of the external electromagnetic environment to the system safety margin,and indicates the defects of the test methods of radiation safety margin in existence.This paper proposes two methods to assess the external electromagn...
