摘要

摘要: 影响射频仿真暗室性能的因素是多方面的,从微波暗室布局、吸波材料性能、天线辐射方向特性3个方面, 利用几何光学法分析了射频仿真暗室静区电平的分布规律,给出了暗室静区主极化电平计算模型.根据某研究所提供的4个频率(0.8GHz,2GHz, 6GHz和18GHz)下吸波材料反射率及天线方向图数据,对该研究所射频仿真暗室的静区电平分布进行了仿真计算,给出了水平极化与垂直极化条件下静区中心面的电平分布.仿真结果表明,采用此方法能快速并准确的适用于射频仿真暗室静区的性能分析.

Abstract: The performance of a RF(radio frequency) simulation anechoic chamber is influenced by many factors. With the geometrical optics methods, the quiet zone performance of a RF simulation anechoic chamber was analysed from the three factors, including microwave anechoic chamber layout, performance of radar absorbing materials and antenna radiation direction character. The calculating model of anechoic chambers quietness on co-polarization was gained and the quiet zone performance was computed in four frequency (0.8GHz, 2GHz, 6GHz, and 18GHz) based on reflectivity of radar absorbing materials and antenna pattern data provided by certain institute.The level layout of the quiet zone center face was gained in horizon and vertical polarization.The computed results accord with technic request, and indicate that this method could rapidly and exactly analyse the performance of a RF simulation anechoic chamber.
