Aiming at the laser angle deception jamming to multi-targets of the multi-fighter group air-to-ground laser guidance attacking,the azimuth features and coding features of guide lasers on multi-targets was theoretical researched.The results show that the combined signal of guide lasers could be decoded by laser angle deception jammer,when the time difference of guide lasers less than the repetition cycle of any one guide laser codes,and all the repetition cycles has the relation of integer multiplication;or when the time difference of guide lasers longer than the decoding time of laser angle deception jammer,the relevant jamming methods of those two situations were discussed as well.Outside of those two situations,the guide lasers could combine to signal of pseudo random sequences code,then the laser angle deception jammer was unable to decode the combined signal or jamming.
