摘　　要：为了研究电磁脉冲对弹载平台上装天线的耦合效应,采用CST电磁仿真软件建立了典型弹载平台结构和两类弹载微带天线的模型,仿真计算了微带天线上装弹载平台前后的辐射电磁特征,以及天线在不同电磁脉冲辐照下的耦合电压响应。仿真结果表明,弹载平台结构能够增强微带天线在工作频率的辐射特性,两天线上装平台后的窄谱高功率微波耦合电压峰值相对单天线分别增大了5%和10%,其电磁脉冲防护设计应以天线上装平台后的最大耦合响应作为安全阈值。In order to study the coupling effects of electromagnetic pulse on missile-borne antenna,the model of typical missile-borne platform structure and two types of missile-borne microstrip antenna are established by employing the CST electromagnetic simulation software.The radiation electromagnetic characteristics of the antenna before and after being mounted on the missile-borne platform,and the coupling voltage response of the antenna irradiated by different electromagnetic pulse are calculated.The simulation results show that the structure of missile-borne platform can enhance the radiation characteristics of the microstrip antenna at the operating frequency.Compared to the single antenna,the peak coupling voltage of HPM-NS of two antennas mounted on the platform increase by 5%and 10%.The maximum coupling response of the antenna mounted on the platform should be taken as the safety threshold for the electromagnetic pulse protection design of the antenna.
