为有效评估激光角度欺骗式、高重频欺骗式和高重频压制式3种有源干扰的干扰效果，以某过重力补偿比例制导导弹为研究对象，开展了3种有源干扰弹道仿真研究。重点建立了激光能量密度模型、激光大气透过率模型、比例导引头视场角关系模型、导引头能量跟踪模型、过重力补偿比例导引律生成模型和导弹控制律模型，结合导弹运动学与动力学方程将仿真系统构成闭环回路。而后，以干扰机布设方位、布设距离和干扰激光能量为仿真变量，实现了3种有源干扰的全弹道仿真。结果表明，侧向布设干扰机，适当增大干扰机的布设距离，增大干扰激光能量能增大脱靶量，可以取得较好的干扰效果。该仿真系统能够为光电对抗效能评估提供平台，为**装备的战术使用提供参考。

To effectively evaluate the effects of three kinds of active laser jamming modes of angle deception, high-repetition-frequency deception and high-repetition-frequency suppression, we made a ballistic simulation of the three jamming modes by taking a certain proportional guidance missile with over-gravity compensation as the research object. The main mathematical models were established, including the models of laser energy density, laser atmospheric transmittance, the view angle of seeker with proportion guidance, the seeker energy tracking, the seeker generating the proportional guidance law with over-gravity compensation, and missile control law, which constituted a closed-loop simulation system by using missile kinematic and dynamic equations. Then, the setting position and setting distance of jammer and the jamming laser energy were taken as simulation variables, and the full ballistic simulation of the three kinds of active laser jamming was completed.Simulation results show that: lateral setting of the jammer, the appropriate increasing of the setting distance and the increasing of the jamming energy can increase the miss distance and achieve a good jamming effect. The simulation system can provide a platform for the effect evaluation of electro-optical countermeasure and a reference for the tactical application of weapons.
