摘要
介绍了电波暗室性能的评估指标归一化场地衰减(NSA),并对电波暗室作了阐述。为了能够快速准确地测量出归一化场地衰减,在3m法暗室和10m法暗室性能评估指标的测试方法的基础上,制定了2种5m法暗室归一化场地衰减的测试方法并进行了测试。最后对测试结果做了分析,并提出一些建议。
It introduces the normalized site attenuation（NSA） indexes for evaluating the anechoic chamber and makes a discussion on an anechoic chamber. For measuring quickly and truly, it designs two different tests about NSA of 5 - meter anechoic chamber based on the testing of 3 - meter and 10 - meter anechoic chamber, analyzes the experiment result and presents some advices.
