转发干扰下DS/FH混合扩频测控信号检测性能
Detection Performance of DS/FH Hybrid Signals for TT & C under Repeater Jamming*
摘要
Abstract
Studying the performance deterioration of DS/FH signals for TT&C(Telemetry Tracking&Command) in interfered environment is of great importance to this novel system. Expressions for probability of detection and false alarming of DS/FH(Direct Spread/Frequency Hopping)signals for TT&C under repeater jamming are de-duced. The probability of false alarming,PSLR(Peak Side lobe Level Ratio)and Correlation Coefficient are simulated and analyzed with different configuration of DS(Direct Spread)and FH(Frequency Hopping)spread-ing gain based on Matlab/Simulink. It is concluded that victim′s receiver is suffered“deception jamming”as long as relative delay time is less than frequency hop duration,which denotes correctness of deduce and offers references for following work.关键词
