A Method of Counter High frequency Laser Jamming of Laser Seeker

Through analyzing the characteristics of wave gate setting and high-frequency laser active deception jamming of the seeker of laser semi-active guidance weapon,a scheme of counter high-frequency laser jamming is proposed by way of judging and sampling out of wave gate and comparing and eliminating in wave gate.The key points,which include judging the jamming,extracting the contrast signal and eliminating the interference,are discussed.The simulation experiment based on Simulink shows that the interference signals in wave gate can be eliminated effectively but does nothing to the guide signals,which indicates that the scheme is feasible in principle.
