摘要
以移动通信的场强预测方法为基础,提出了一种应用于通信对抗试验外场区的超短波电波传播损耗预测模型的修正方法,根据实际测量数据利用最小二乘法求解模型中参数,实现传播模型的本地化,结果证明修正模型能够达到较高的精度。
Based on the method of field strength prediction for mobile communication, a method of model correction for propagation loss prediction of VHF radio wave is presented in this paper. This model can be used in location of communication countermeasure test outfield. The parameters in the model are calculated by least square estimate based on the actual measurement data. The results prove that the localized model can get sufficient accuracy for propagation loss prediction.
