Based on the current counter-jamming situation of laser terminal guidance weapon,the high-repeated frequency jamming is analyzed,and the scheme of counter high-repeated laser active jamming is put forward. By analyzing the math model and concluding its principle,the period of high-repeated frequency is calculated. This principle is the core of the scheme,key points of which are the calculation of the period of high-repeated frequency signals and the determination of the synchronous point of the inverted high pulse repetition frequency signals.The scheme can solve the problem of the active jamming. The scheme and a new kind scheme of laser code which we have put forward compose the integrated scheme of counter laser active jamming to the laser terminal guidance weapon.
