为应对复杂电磁环境下雷达应用需求，提出一种基于混响室的雷达杂波模拟方法，利用电磁仿真软件 FE-KO 构建了混响室模型，分析了搅拌器控制与接收响应周期性的关系，通过随机控制混响室搅拌器在混响室内模拟了具有瑞利分布的杂波信号。实验结果显示，本实验数据分布曲线与瑞利分布曲线有良好的拟合性。

To deal with the requirements of radar applications in complex electromagnetic environ-ment,a new method for emulating radar clutter is proposed based on reverberating chamber. First,the electromagnetic simulation software FEKO is used to analyze the relationship between the stirrer control and cycles of received responses.Then,through randomly controlled stirrers, random signal is generated in the reverberating chamber and clutter signal which has Rayleigh distribution is simulated through modulating the experimental parameters.The result shows that the experimental data distribution curve fits the simulated target distribution curve.
