海面电波传播损耗模型研究与仿真

Study and simulation on sea-surface propagation prediction model

研究了海面电波传播损耗预测模型,指出对该类传播损耗预测的仿真模型宜采用Longley-Rice模型,并对模型作了适应性修正和补充以适应海上编队通信链路的仿真。还推导了Okumura-Hata模型和Longley-Rice模型电波传输损耗预测的具体算法,数值仿真结果显示本文提出的方法预测结果与实测数据相符,最后给出对1 km以内和飞机飞行高度在10 km以上时的修正和补充方法。

For the simulation of ship formation communication channel, a improved Longley-Rice model is presented to predicte the loss of radio wave propagation along the sea surface. The computational procedure of the Okumura-Hata model and the Longley-Rice model is discussed. By comparing with the test data, the simulation results show the validity of the prediction model.
