摘　　要：针对选频分集散射通信抗干扰性能评估准确性提升,提出了一种自适应选频分集抗干扰性能分析方法,基于抗衰落分集接收解调算法建立了选频抗干扰分析模型。通过仿真分析可获得选频分集准确的抗干扰性能,并根据不同的干扰特性得到了量化的分析结果。仿真结果表明,该自适应选频分集抗干扰分析方法优于现有的散射通信抗干扰分析方法,便捷有效,能够显著提升抗干扰性能评估的准确性。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 antijamming 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.
