摘要
本文通过实测得到理论参考值,再利用概率密度函数(PDF)模型定性分析了混响室内场的分布统计特性。本次实验采用的混响室工作频率为1GHz—9GHz,尺寸为1.1 m×0.7m×0.6m(长×宽×高),实验结果将参照模型进行分析,并且用威布尔图对实验数据进行验证,在一定的误差允许范围内,最终验证混响室内场的功率密度的pdf满足威布尔分布。
A set of measurements for a type of statistical model that describe the field power density inside a reverberation chamber（RC） are presented. The model is a probability density function （PDF）. The type of measurements are analyzed with respect to the corresponding ideal theoretical model. The function is observed over a frequency range that allows for the conditions in the chamber to vary from undermoded operation to overmoded operation（1GHz-9GHz）. Ultimately,the paper states that the distribution of the field power density at a certain position in the RC fits a Weibull distribution.
