摘要
短波天波信道(时变信道)的衰落特性是影响远距离短波通信质量的主要因素,准确分析预测短波信道传输特性是通信成功的基础。结合工程试验分析了影响短波通信质量的诸多因素,选择最佳的通信信道,成功实现了远距离短波地空通信。分析预测-选择信道频率-静态测试-短波通信的方法,对短波通信系统远距离通信能力考核试验具有参考价值。
Fading characteristic of HF sky-wave channel is the main factor to influence long range HF communication quality. Predicting HF propagation characteristic precisely is an element for successful communication. Factors influencing HF communication quality are analysed along with engineering experiment. By choosing the best channel long range air-ground HF communication is realized. The method of predicting-frequency preference-static test-communication can provide good reference for long range communication test of HF systems.
