Abstract

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.
