摘　　要：为了确定采用激光半主动制导的末段脉冲修正迫弹的攻击区域,建立了导引头目标捕获域模型,分析了迫弹受到的脉冲控制力及控制力矩,推导出六自由度有控弹道方程组,给出了脉冲最大修正区域模型,并提出了攻击区建模和仿真的方法。利用上述模型对给定启控条件下的攻击区进行了仿真计算,得到了不同导引头参数及不同脉冲冲量作用下的攻击区域图。结果表明,提供的模型及仿真方法适用于该类弹箭攻击区的求解,对于导引头、脉冲发动机的设计也有一定的参考价值。In order to determine the attack area of semi-active laser guided mortar projectiles with impulse thrusters for terminal correction, the model of acquisition area for the seeker was established. Based on the analysis of impulse forces and impulse moments, the 6-DOF equations for trajectory under control were deduced, and the model for the maximum correction area of impulse thrusters was given. Thus, an approach for constructing the model of attack area and its simulation method were proposed. With the models, attack area simulations under a certain start control condition were carried out. Figures of attack area for different seeker＇s parameters and different pulse jets impulse were obtained. The results indicate that the models and the simulation method are applicable for the calculation of similar projectiles＇ attack area, also helpful for the design of seeker and impulse thruster.
