| 摘要: |
| Studying the performance deterioration of DS/FH signals for TT&C(Telemetry Trac
king & Command) in interfered environment is of great importance to this novel s
ystem. Expressions for probability of detection and false alarming of DS/FH(Dir
ect Spread/Frequency Hopping) signals for TT&C under repeater jamming are deduc
ed. The probability of false alarming, PSLR(Peak Side lobe Level Ratio) and Cor
relation Coefficient are simulated and analyzed with different configuration of
DS(Direct Spread) and FH(Frequency Hopping) spreading gain based on Matlab/Si
mulink. It is concluded that victim′s receiver is suffered “deception j
amming” as long as relative delay time is less than frequency hop duration, whi
ch denotes correctness of deduce and offers references for following work. |

| Abstract: |
| 分析直扩/跳频(DS/FH)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。推导了转发干扰环境下DS/FH测控信号的检测概率和虚警概率表达式。以M
atlab/Simulink为平台搭建了检测性能仿真系统，对检测概率、主副旁瓣比和相关系数进行
了仿真分析，指出只要转发时延小于一个跳频驻留，就能实现“欺骗”干扰，验证了理论推
导的正确性，为进一步研究提供了参考。 |
