| 摘 要： | 超远程散射通信应用需求日益增加，然而通过实测验证，目前的传输损耗预测方法在超远程散射链路预测方面存在较大偏差.文中基于ITU-R P.617-3（China-ZHANG）方法针对超远程散射传播特点进行分析，给出了一种适用于超远程散射链路的传输损耗修正预测方法.通过多条实际链路测试验证，证明了该修正方法的有效性和准确性，为超远程散射通信系统设计提供了可靠的参考依据.

| Abstract: | The demands for ultra long-distance troposcatter communication is greatly increased. However, according to actual measurement, current methods of transmission loss prediction is not suit for ultra long-distance links. In this paper, a correction method of the transmission loss prediction for ultra long-distance troposcatter links is mainly discussed. The proposed method is developed based on ITU-R P.617-3. Through practical experiments and measurements, it is proved that the proposed method is effective and accurate. This correction method could provide reliable reference for the design of ultra long-distance troposcatter communication systems. |
