Abstract

Abstract:

In order to improve the evaluation accuracy of anti-jamming performance of frequency selection diversity in troposcatter communication， an analysis method of adaptive frequency selection diversity anti-jamming performance is proposed. Based on the anti-fading diversity reception demodulation algorithm， a frequency selection anti-jamming analysis model is established. Through simulation analysis， accurate anti-interference performance of frequency selection diversity is obtained， and quantized analysis results are obtained according to different interference characteristics. The simulation results show that the adaptive frequency selection diversity anti-jamming analysis method is superior to the existing troposcatter communication anti-jamming analysis method， convenient and effective， and significantly improves the accuracy of anti-jamming performance evaluation.

Key words: troposcatter communication, adaptive frequency selection, diversity reception, anti-fading demodulation, performance of anti-jamming
