摘　　要：为检验电台类装备在高空核爆电磁脉冲(high-altitude electromagnetic pulse,HEMP)环境下的生存能力,降低系统电磁脉冲易损性评估中的不确定度,设计了系统级HEMP辐照试验方案及易损性试验评估流程,建立了基于故障树模型的电台电磁损伤评估算法.以欧讯SG-7200型超短波电台的电磁易损性评估为例,应用电磁损伤评估算法开展威胁级辐照试验.试验结果表明:电台在50 kV/m的辐照试验中发生跳频现象,通信故障;在故障树模型中,根据多次试验数据得到该型电台在50 kV/m的威胁级辐照试验中系统失效概率为78.83%.To test the survivability of radio equipment in the environment of high-altitude electromagnetic pulse(HEMP)and reduce the uncertainty of system electromagnetic pulse vulnerability assessment,the system level nuclear electromagnetic pulse irradiation test scheme and vulnerability test assessment process are designed,and the radio electromagnetic damage assessment algorithm based on fault tree model is established.Taking the electromagnetic vulnerability assessment of SG-7200 ultra short wave radio as an example,the threat level radiation test is carried out by using the electromagnetic damage assessment algorithm in this paper.The test results show that the radio frequency hopping phenomenon and communication failure occur in the 50 kV/m radiation test;in the fault tree model,according to the test data,the failure probability of the system is 78.83%in the 50 kV/m threat level radiation test.
