摘　　要：通过实验验证了混波室内场的统计特性。给出了基于矢量网络分析仪的测量混波室可重复性的试验方法与配置。用矢量网络分析仪的方法对不同的发射天线方向进行了测试与比较。结果表明:发射天线的方向对混波室测量可重复性有较大的影响,对准混波室的角落和搅拌器时的测量可重复性较好。In this paper, the field characteristic of the reverberation is tested. Experimental method and configuration which based on Vector Network Analyzer （VNA） of measurement repeatability are provided. The repeatability of different transmit antenna orientation is measured, and the result proves that the orientation of transmit antenna has greater effect on the measurement repeatability, when then transmit antenna direct to the chamber corner and the stirrer is much better than the other orientation.
