Real-Time Frequency Selection System in HF Communication Based on Backscatter Sounding and Interference Monitoring

WANG Jun-jiang,LIU Wen,JIAO Pei-nan(1.China Research Institute of Radiowave Propagation,Qingdao,Shandong 266107,China;2.National Key Labaratory of Electromagnetic Environment,Qingdao,Shandong 266107,China)  
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.
