摘　　要：目指示误差是激光末制导炮弹射击误差的主要组成部分,研究目标指示误差对于提高激光末制导炮弹的射击精度具有重要意义。针对激光末制导炮弹对运动目标射击的特点,分析了激光末制导炮弹目标指示误差的组成,采用自回归建模方法建立了目标指示误差频谱分析模型,设计了仿真目标指示误差的数字滤波器,并给出了数字滤波器参数的估计方法。最后以某型号激光末制导炮弹为例进行了仿真计算,所得仿真结果与实测数据相符。该模型已在激光末制导炮弹训练模拟器中得到了应用。Target designating error is the main factor of firing error of laser terminal guided projectile, and it is very important to study target designating error for improving firing accuracy of laser terminal guided projectile. According to the characteristics of laser terminal guided projectile shooting moving target, the composition of target designating error was analyzed, the model of frequency spectrum of designating error was built by using auto -regressive modeling method, digital filter for simulating target designating error was designed, and the method of parameter esti- mation of digital filter was put forward. At last, a laser terminal guided projectile was taken as an example to simulate target designating error, the simulation result tallied with testing data. The simulation model has been applied to training simulator of laser terminal guided projectile.
