摘　　要：针对降雨环境下的无线电引信电磁回波信号的衰减及干扰的问题,建立毫米波引信降雨环境电磁衰减验证模型。该模型首先分析无线电电磁强度在降雨粒子中传播的衰减特性,建立多层降雨粒子的毫米波引信电磁衰减计算方法;其次仿真模拟降雨粒子空间中毫米波电磁的衰减,得到电磁频率、电磁衰减率与降雨强度的关系;最后通过在大雨与暴雨环境的电磁回波测试数据与模型的比较分析,验证了模型精度达到85%以上。该验证模型为无线电引信的抗降雨干扰设计提供了技术支撑。According to the attenuation and interference of radio fuze electromagnetic echo signal in rainy environment,a verification model of electromagnetic attenuation of millimeter-wave fuze in rainfall environment is established in this paper.The model firstly analyzed the attenuation characteristics of the millimeter-wave fuze electromagnetic intensity in the rainfall particles,and a calculation method was established based on electromagnetic attenuation in the multiple layers of rainfall particles;Secondly,the attenuation of millimeter wave electromagnetic in rainfall particle space was simulated,and the relationship between electromagnetic frequency,electromagnetic attenuation rate and rainfall intensity was obtained;Finally,through the comparison analysis of the electromagnetic echo test data and the model in heavy rain and rainstorm environments,the model accuracy was verified over 85%.The verification model provided a method support for the anti-rain interference design of radio fuze.
