摘　　要：分析DS/FH(直扩/跳频)混合扩频测控信号在干扰环境下的性能对该新测控体制的研究具有重要的意义。推导了多音干扰环境下DS/FH测控信号的检测概率和虚警概率表达式,仿真分析了不同直扩增益、跳频增益组合情况在不同多音干扰条件下的检测性能,得到了一些有意义的结论,为进一步研究提供了参考。Analysing the performance of DS/FH hybrid spread spectrum TT＆C signals in jamming environment is important for the study of this novel TT＆C system. In this paper expressions for detection probability and false alarming probability of DS/FH TT＆C signals under MTJ （Multi- Tone Jamming） are deduced, the detection performance is simulated and analysed with different configuration of DS and FH spreading gain, and valuable conclusion is drawn, which offers references for further research on DS/FH signals application in TT＆C system.
