摘要
通信距离小于100 km的对流层散射线路关于信道特性的测量数据较少,现有的算法不能快速预计传输损耗。为了解决这个问题,试验通过对多条不同距离下散射信道的实测,分析了电波传播的几种模式,与现有算法进行了对比,提出了对流层散射传输损耗的一种简便工程算法。试验结果表明,提出的算法可以快速预计传输损耗。
The measurement data on the channel characteristics for troposcatter communication in the distance of less than 100 km are fewer,the exiting algorithm can’t quickly predict the transmission loss.To solve the problem,based on the practical measurement of multiple scattering channels in different distances,several radio wave propagation modes are analyzed.Compared with the existing algo-rithm,a simple engineering algorithm of troposcatter transmission loss is proposed.The experimental results show that the proposed algo-rithm can quickly predict the transmission loss.
