摘要
表面波导使电磁波产生异常传播,其对通信设备具有显著的影响,本文采用抛物型方程理论及算法模拟电磁波的传播损耗,利用通信距离评估模式计算通信设备的最大通信区,利用通信接收机有效配置区的计算方法给出通信接收机有效配置区和通信干扰压制区,分析了表面波导对超短波通信对抗的影响。
Electromagnetic wave propagates abnormally in the duct condition. It has prominent influence on communication equipment. Parapolic equation method and split-step Fourier method were used to model electromagnetic wave propagation loss, communication zone evaluation model was used to calculate maximal communication zone, the methods to calculate effective configuration zone of communication receiver and communication jamming suppressive zone were used in this paper. The effect of duct condition on ultrashort communication countermeasure was analysed.
