摘要
主要研究混响室内场分布的空间特性统计模型,对自制的混响室内场分布的空间相关特性进行测量,与理论模型空间相关函数SCF进行对比分析。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,多模或过模状态的操作。从这些实验结果中可以得到混响室操作的低频限制标准。
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 chamber to vary from non - ideal, multi - moded operation to ideal, overmoded operation. A criterion for the low - frequency limit of chamber operation is proposed from these observations.
