A Recognition Approach of Gate-Pull Jamming

Aiming at the insufficient existing fundamental,combined with the structure characteristic of deception jammer,generation mechanism of gate-pull jamming and its action mechanism to the concrete radar receiver,the variation of radar receiving signal's characteristic is anaylzed when jamming enteres the system.The statistical and fine fetures of the receiving signal is extracted to detect jamming,and theoretical model of jamming identification is studied according to the interaction and time-varying characteristic between the real echo and jamming in the process of gate-pulling.A gate-pull jamming subtype identification approach is formed based on processing which provids theoretical basis to further improve radar system anti-jamming ability.In the end,experiments show that this method is feasible and has comparatively better correction identification ability.
