跳扩频信号抗多音干扰性能分析

Performance analysis of DS/FH signal against multi-tone interference

DS/FH(直扩/跳频)跳扩频信号兼具有扩频和跳频的抗干扰增益,在实际的应用中有着越来越广泛的应用,为了分析跳扩频信号抗干扰能力的目的,采用通信技术作为依托,通过模拟仿真得到验证结果;做了跳扩频信号抗音调干扰的仿真实验,获得多音干扰效能与干扰频点位置以及音调个数均有相干关系的结果,得到一些有意义的结论,能为接下来的研究提供指导性意见。

DS / FH signal has anti-interference gain in both spread spectrum and frequency hopping, and more wide use in practical applications. In order to analyze the anti-interference ability of the spread spectrum and frequency hopping signal, the communication technology is adopted as the basis. A verification result was obtained through analog simulation. A simulation experiment for anti-tone interference of DS/FH signal was done. A result that multi-tone interference effectiveness, interference frequency point position and tone number have coherent relationship was achieved. Some meaningful conclusions were got. The analysis result provides a guiding idea for the further research..
