| 摘 要： | 国际电磁兼容标准给出了标准距离的归一化场地衰减(NSA)的理论值,但在实际应用中需要知道非标准距离的理论值。根据归一化场地衰减的定义,介绍了一种NSA理论值计算模型。对该模型进行了数学推导,得出了NSA的计算公式,并通过计算机编程进行了计算。计算结果表明:计算误差小于0.1dB,满足标准要求。该模型可以用于仿真暗室中不同测试距离、不同收发天线高度的NSA理论值计算。

| Abstract: | The whole theoretical data of normalized site attenuation(NSA) can be found in the international electromagnetism compatibility standards when the test distance is normal,however,we need to attain the data of nonstandard test distance about NSA in the practical application.The theoretical calculation model about NSA is introduced according to the definition of NSA.The program of mathematic model is designed and calculated in virtue of the computer.The calculation results show that the calculation error is l... |
