摘　　要：对流层散射通信作为一种典型的变参信道,具有链路损耗大、存在多径时延等传输特性;除此之外,在实际使用过程和多次通信试验中,发现了"雨增"的反常传播现象。对于在不同地域和气象条件下的链路损耗特性进行研究,特别是对于"雨增"现象进行探索性研究,对于后续散射通信链路的建设、尤其是固定站的建设具有借鉴意义。As a typical variable parameter channel,tropospheric scatter communication has the characteristics of large link loss and multipath delay.Besides,the anomalous propagation phenomenon of"rain increase"has been found in the actual application process and multiple communication experiments.The study of link loss characteristics under different geographical conditions and meteorological conditions,especially for the phenomenon of rain increase,is helpful for the construction of the subsequent scatter communication links,especially for the construction of fixed stations.
