摘　　要：提出了一种基于HF电离层返回散射探测和干扰监测的短波通信实时选频系统.利用返回散射快速扫频及返回散射电离图自动判读技术,实时获取短波通信的可用频段信息,基于实时干扰监测结果,利用基于时间可用度的自动干扰分析技术得到干净信道信息,两种信息融合实时选择通信频率.文中给出了一些具体链路的通信选频试验结果,并对某些特殊情况下的实时选频效果进行了深入分析,试验结果表明了该系统的有效性.A real-time frequency selection system based on backscatter sounding and interference monitoring for the short-wave communication is developed in this paper. Using fast sweeping-frequency and backscatter ionogram auto-scaling techniques, the usable frequency range is obtained, and, the clean channel is obtained simultaneously by interference automatic analysis technique based on time-availability. Then,the real-time communication frequency is selected by the fusion of the two kinds of information above. Some test results of specific communication links are given and further analysis of special cases is presented. The experimental results show the effectivity of the proposed system.
