摘要
文章首先经过推导和计算,得出了一套计算紧缩型暗室的归一化场地衰减(NSA)理论值模型。通过该模型,可以计算出任意给定参数下的NSA理论值;然后把模型计算的数据和标准数据做比较,分析误差来源;最后结合实际测量结果,考察模型的应用效果。
A NSA model of impact anechoic chamber ispresented herein theoretically.With thismodel,NSA theo鄄retical data can be computed under arbitrary parameters.Then contract the error between the calculated data and the measured data.Finally,the application scope of the model isdiscussed according to the measured data.
