本文简述了微波暗室静区与反射电平的基本概念,论述了空间驻波法测量暗室反射电平的基本原理和方法,重点讨论了自由空间电压驻波比法测量反射电平的数据简化处理新方法。结合我所微波暗室的测试经验,指出了微波暗室测试中应注意的问题,最后给出了我所微波暗室反射电平的实测结果。 In this paper, the basic concepts of quiet zone and reflection level of microwave anechoic chamber are briefly introduced. The basic principle and method of measuring the darkroom reflection level by space standing wave method are discussed. The simplified data measurement of reflection level by free space voltage standing wave ratio method Deal with the new method. According to the test experience in my anechoic chamber, the problems that should be paid attention to in the anechoic chamber are pointed out. Finally, the measured results of the anechoic chamber in my anechoic chamber are given.
