Research on Anti-jamming Capability Evaluation Method for Spread Spectrum TT&C Signals

Based on the analysis of active jamming mechanism and spread spectrum Tracking Telemetry and Command(SS TTC) signals processing principle,a method using the ambiguity plots effective areas and the incision areas at a certain level to evaluate inherent anti-jamming capability of SS TTC signals is put forward.The smaller the computed areas become,the stronger the anti-jamming performance gets.Simulation results show that the proposed metrics are effective to assess signals anti-jamming performance.The methodology is computable,which provides reference for signals anti-jamming capability evaluation.
