摘    要:随着车载无线系统上装无线设备电磁环境日益复杂,设备间电磁干扰日益严重,采用仿真技术进行天线布局优化可以有效减小设备间干扰。本文分析了影响车载天线系统天线布局的主要因素,得出天线优化布局的优化目标为天线间的耦合度和方向图失真度,建立了天线布局优化模型,采用改进的遗传算法对车顶天线布局进行优化设计,在电磁兼容设计初期得出粗略的最佳布局方案,使其满足电磁兼容性能要求,降低了天线布局设计的难度,并设计了电磁兼容优化仿真软件,实现了车载系统的优化布局仿真,达到工程实际要求。

关 键 词:电磁兼容  优化仿真  改进遗传算法

Abstract:As the electromagnetic environment of wireless system on a vehicle has been more and more complicated, the electromagnetic interference between equipments has been more and more serious, so we adopt Optimization and emulation technology as to reduce the interference between equipments This paper analyses the principle elements that affect the capability of the antennas disposing on a vehicle, obtaining the result that the optimum objects are degrees of coupling in antennas and degrees of distortion of directional diagram and creating the antennas layout model. We use advanced genetic algorithm to perform antennae's position optimum design so that we could get optimally antennas layout scheme in the first stage of Electromagnetic Compatibility design and satisfy the requests of electromagnetic compatibility and reduce the designed difficulty of antennas layout. The design of optimum design software in electromagnetic compatibility is also made. The implementation of the optimization in electromagnetic compatibility achieves the requests of proiects.
Keywords:Electromagnetic Compatibility  Optimization  Genetic Algorithm
