基于FEKO的超短波通信对抗系统电磁兼容性仿真分析

摘要

This paper analyzes the electromagnetic compatibility（EMC） problem of ultra-short wave（USW） communication countermeasure system,sets up a mathematical model of minimum configuration distance for EMC among systems,performs the modeling and simulation to the direction speciality of jamming antenna（log periodic dipole antenna） by means of FEKO software,calculates the relationship between the jamming power at the input terminal of communication receiver in reconnaissance station and the configuration distance,gives the minimum EMC configuration distance between the communication jamming station and reconnaissance station.%对超短波通信对抗系统的电磁兼容性问题进行了分析,建立了系统间电磁兼容性的最小配置距离数学模型,采用FEKO软件对干扰天线（对数周期偶极子天线）方向特性进行了建模与仿真,计算了侦察站通信接收机输入端的干扰功率与配置距离间的关系,给出了通信干扰站与侦察站之间的最小电磁兼容性配置距离。
