基于实测数据的激光高重频干扰效果数学仿真

为了解决激光高重频干扰效果评估的问题，设计了高重频激光干扰导引头实物实验，利用实测数据建立了干扰效果模型。通过比较实验情况与数学仿真战情中导引头工作状态的区别，验证了模型的可信度。分析了光斑大小和能量分布、激光入射光线与导引头轴线夹角、导引头接收能量密度等因素对制导信号生成的影响。采用蒙特卡洛方法对激光高重频引诱干扰和扰乱干扰情况下制导炸弹进行了弹道仿真，对其落点分布进行了分析。

High-repetition-frequency laser jamming effect mathematical simulation based on measured data

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.
