摘　　要：为了研究调幅波对无线电引信的电磁环境效应,分析了无线电引信混频原理及高频电路输出信号特征,解决了调幅波的波形调制问题,建立了辐照调幅波的波形表达式,形成了无线电引信辐照电磁环境,探索了不同频率调幅波对引信的意外发火场强干扰阈值及其变化规律。结果表明:辐照频率在引信本振频率外一定范围内引信误炸干扰阈值低于10V/m,随着辐照频率与引信本振频率偏移量增加误炸干扰阈值呈增大趋势;调幅波辐照不会对引信电子部件产生硬损伤,也不会导致引信瞎火。To investigate the elecromagnetic environment effects of the amplitude modulation wave on radio fuze,the mixing theory and the output signal character of high frequency circuit are analyzed,and the problems of waveform modulate are resolved.The modulate waveform expression and the radio fuze radiation electromagnetic environment is established.The experiment is done to find out the threshold field intensity for accidental explosion and the variable rules of the radio fuze.The conclusions show that when radiation frequency is appressed with the vibration frequency,the threshold field intensity is less than 10V/m.With the frequency deviation increasing,the threshold field intensity becomes larger.The electronic components of the radio fuze is not destroyed.
