| 摘 要： | 研究了Longley-Rice电波传播模型以及各参数的实际意义,指出了Longley-Rice模型没有考虑接收机附近的因素对传播损耗的影响,因此会导致接收机附近的电波传播损耗的计算误差。对Longley-Rice模型做了改进,建立了等效散射模型,描述了接收机附近的损耗情况。改进的模型能够减小计算误差,在一定程度上提高预测的精度。

| Abstract: | The Longley-Rice radio wave propagation models and parameters are studied.Due to ignorance of factor around receiver in Longley-Rice model,it creates error in calculating loss of radio wave propagation around receiver.The affect to propagation loss is presented to predict the loss of radio wave propagation.Improvement to Longley-Rice model is performed through modeling equivalent scattering model,which describes loss of radio wave propagation around receiver.The modified model can reduce error and improve a... |
