混响室的空间相关特性测量
Measurement of Spatial Correlation Characteristics in
Reverberation Chamber
摘要 主要研究混响室内场分布的统计模型,对空间相关函数SCF进行了测量研究,并将测量结果与理论模型进行对比分析,得出一个低频限制的临界频率点。研究结果是在一定频率范围内观察得到的,即从不理想、欠模状态到理想、过模状态的操作。从这些实验结果中可以得到混响室操作的低频限制标准。

Abstract A set of measurements for statistical model(Spatial Correlation Function,SCF)
that describe a component of the power density inside a microwave reverberation
chamber are presented. This type of measurements is analyzed with respect to the
corresponding ideal theoretical model. The functions are observed over a frequency
range that allows for the conditions in the (experimental and simulated) chamber to
vary from non-ideal, multi-mode operation to ideal, over-mode operation in the high
frequency limit. A criterion for the low-frequency limit of chamber operation is
proposed from these observations.
