| 摘 要： | 根据谐振腔理论,分析了理想情况下影响源搅拌混响室性能的主要因素,通过数值计算对其进行仿真验证,确定了影响混响室场均匀性的主要因素有激励天线的极化方向,摆放位置以及激励源的位置数等;在此基础上提出了一种可行的源搅拌方案,通过实验的方法,在满足一定采样数情况下,实现了混响室较好的场均匀性;同时借助K-S拟合对源搅拌混响室测量场值的统计特性进行了分析,结果表明:源搅拌混响室的一维场分布服从瑞利分布。

| Abstract: | According to the source stirring reverberation chamber(SSRC)theory,the key factors influencing its performance and the simulation of the SSRC field structure is analyzed.The antenna polar direction,antenna position and the numbers of source are the main factors to affect the filed uniformity,and simulation of the model and calculation of the result prove that the field uniformity will be achieved by altering the factors.A source stirring scheme is proposed.Through the experiment,valuable data for SSRC desig... |
