摘　　要：论文介绍了短波发信节点通信覆盖能力的计算方法,选取海上短波发信节点,对6m短波鞭天线4kW输入功率发信时覆盖区域内的射频信噪比分布进行了仿真计算,给出了采用10m短波宽带直立天线收信时,不同季节、不同时间、不同太阳黑子数、不同频率的通信覆盖距离及典型收信点处的最高可用频率(MUF),对评估海上短波发信节点的通信保障能力具有参考意义。A computing method of shortwave transmitting node communication covering ability is proposed in this paper,a HF transmitting node on sea is selected and the radio SNR distribution in covering area is simulated and calculated on the condition of 6m HF whip antenna with a output power of 4kW,the communication covering distance under different season,time,NSS,frequency and typical receiving node＇s MUF are proposed when receive signal by a 10 m HF broadband vertical antenna,which has a reference significance to assess the communication guarantee ability of HF transmitting node on sea.
