摘　　要：在武器装备电磁辐射效应预测研究的背景下,为提高试验可重复性,减小模型验证误差,给出一种雷达电磁辐射阻塞效应敏感判据.结合理论与试验,将有效干扰概率作为效应敏感参数,探究其变化规律,进而得到具体的敏感判据.结果表明,在不同频率正弦波干扰下,有效干扰概率的变化规律基本一致;理论上可将有效干扰概率50%作为电磁辐射阻塞效应敏感判据;实际试验中有效干扰概率为40%~60%时,即可认为受试雷达处于敏感状态,测试误差小于1dB.In the background of weapon equipment electromagnetic radiation effect prediction,in order to improve the repeatability of the test and reduce the error of checking model,a susceptibility criterion of electromagnetic radiation blocking effect is explored.Combined with theory and experiment,the effective interference probability is taken as an effect susceptibility parameter to explore its variation law,and then the specific susceptibility criterion is obtained.The results show that under the different frequency sine wave irradiation,the change rule of the effective jamming 50%probability of the tested radar is basically the same.Theoretically,the effective jamming probability can be used as the susceptibility criterion of the blocking effect of electromagnetic radiation.When the effective jamming probability is 40%~60%in the actual test,the radar under test can be considered to be in a susceptible state,and its test error is less.than 1 dB.
