Abstract: In order to solve the problem of the high-repetition- frequency laser jamming effect, experiments of the high-repetition-frequency laser jamming the real laser seeker was designed, models of the jamming effect based on measured data were built. By comparing the different working state between experimental condition and mathematical simulation scenario, the reliability of the model was verified. The effect of the guidance signal on the different laser spot size and energy distribution, the different angle between incident ray and seeker axis, and the different received energy density was studied. By using Monte Carlo method, the laser guided bomb trajectory was simulated under the high-repetition-frequency laser bait jamming and disturbing jamming, the impact point distribution was analyzed.
