源搅拌混响室天线布置方式实验研究

摘要

根据谐振腔理论,分析了理想情况下影响源搅拌混响室性能的主要因素.通过实验方法,对提出的两种源搅拌方案从场均匀性和统计特性两方面进行分析.经过对采样数据处理可知,在一定数量采样值的情况下,这两种方式都可以实现较好的场均匀性,同时借助K-S拟合对测量值的统计特性进行了分析,结果表明源搅拌混响室的一维场分布服从瑞利分布,通过对两种天线布置方式的实验对比,为源搅拌混响室的实现与开发提供了详实的实验基础.%According to the resonant cavity theory, the key factors influencing source stirred reverberation chamber performance are analyzed. Two source stirred scheme are proposed. Through the experiment, the valuable data for SSRC design and performance evaluation is provided. In the 80 ～ 1000 MHz frequency range, with the smallest sample number of the request, a better field uniformity is obtained. Meanwhile, the statistical characteristics of the electric field magnitude obeys Rayleigh distribution, which performed by the KolmogorovSmirnov (K-S) fitting method. Through a series of experiments, a detailed experimental base is provided to realize the source stirred reverberation chamber.
