短波天波通信性能预测软件的接收场强预测准确性对比与分析

摘要

Based on the global 181 median sky wave ifeld strength data issued by ITU in Data Band D1/1, this paper analyzed the precision of median ifeld strength calculated by VOACAP and REC533 with different parameters and different great-circle route distance. The error ranges of prediction results were estimated and the basic characteristics were obtained. Then, selection principles of the two algorithm software, parameter configuration suggestions and the prediction results of adoption standard were proposed.%以ITU在Data Bank D1/1中发布的全球181条链路实测短波天波接收场强中值数据为基础，对VOACAP和ITU-REC533两种预测软件在不同计算参数配置和不同链路大圆距离情况下得出的接收场强月中值的准确度进行统计分析，得出预测误差的范围估计和基本特性，在此基础上提出两种算法软件的选取原则、参数配置建议和预测结果的采信标准。
