摘　　要：分析扩频测控信号在干扰环境下的性能对测控体制的研究具有重要的意义。推导音调干扰环境下DS测控信号的伪码跟踪误差表达式,以Matlab/Simulink为平台搭建了伪码跟踪性能仿真平台,仿真分析了不同干扰条件、不同增益分配下的DS/FH混扩测控信号伪码跟踪性能,验证了理论推导的正确性,为进一步研究提供了参考。Studying the performance deterioration of DS/FH(Direct Sequence/Frequency Hopping) signals in interfered environment is of great importance to the system for TT&C.Expressions for code tracking performance of DS signals under multi-tone jamming are deduced.The simulation platform is constructed with Matlab/Simulink,and the performance of code tracking is simulated and analyzed under different jamming conditions as well as different gain configuration.Monte-Carlo simulation and theoretical derivation results are consistent with each other and the valuable conclusions which can offer some reference to the DS/FH signal application for TT&C are obtained.
