摘要：
The conversion of radiated field strength at different distance in semi-anechoic chamber is analyzed. Firstly, the empirical model based on the logarithmic distance path loss is introduced. Secondly, theoretical models of radiation field in the same site or the different site at different distance are obtained through calculating the difference of normalized site attenuation (NSA) with different transmit / receive antenna distance. The engineering model in the different sites is also discussed. The experimental data is used to analyze the conversion of radiation field strength at different distance. The experimental results show that it is not appropriate to introduce a determinate correction factor in dealing with the conversion of equipment under test measured in the 3m and 10m semi-anechoic chamber.
