摘要
在混响室和GTEM室中用连续波对同一敏感电路进行电磁辐照,测量电路的干扰阈值,统计分析实验数据,绘出混响室和GTEM室中电路干扰阈值的最小值、最大值和平均值随频率的变化曲线。据此对混响室和GTEM室的相关性进行定性分析;通过计算Pearson积差相关系数,对混响室和GTEM室的线性相关性进行定量分析。
Electromagnetic radiation tests of a sensitive circuit was done by using continuous wave in reverberation chamber and GTEM cell. The interference threshold of the circuit was measured. The experiment data were statistically analyzed. The change curve of the minimum, maximum and average of the interference threshold of the circuit in the reverberation chamber and the GTEM cell with the frequency was plotted. Quantitative analysis of the linear correlation of the reverberation chamber and the GTEM cell was done by calculating Pearson＇s product moment correlation coefficient.
