Study on counter high-repeated frequency laser jamming scheme

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.
