摘要

Aims at some troubles in traditional electromagnetic environment effects test method, such as large expense, large antenna size in low frequency and difficult operations, a current injection method is proposed to test the electromagnetic vulnerability ( EMV) of guided weapons. The detail theoretical calculation and simulation are carried out and the frequency limitation of the method was given. The method proposed has some advantages, such as low cost, simple operation and is suitable for the electromagnetic effect tests of conventional weapons also.%针对传统发射机和天线模式进行电磁环境效应试验耗资巨大、在甚低频以下频段天线尺寸太大、试验操作困难等难题,根据电磁场理论中的等效原理,提出了应用电流注入法测试制导武器(制导导弹、制导炸弹和火箭弹)电磁易损性(EMV)的试验方法.通过应用同轴线复电位理论进行了推导,并应用电磁场仿真软件进行了仿真验证,给出了适用频率上限的计算方法.本文提出的这种测试方法具有试验设施造价低廉,试验方法简单的特点,适用于常规兵器的电磁境效应测试.
