摘　　要：针对机载激光探测器的目标位置定位精度问题,提出了改进目标定位算法,在半自动激光末端修正弹弹道修正过程中实时获取地面目标的精确位置,根据弹丸的位置、姿态和视线角度,建立了目标定位模型。通过蒙特卡罗方法分析了不同象限仰角下弹丸位置、姿态和视线角测量误差对定位精度的影响。仿真结果表明,瞄准线角度的测量误差对定位精度影响最大,定位精度随象限仰角的增大而减小。A target localization algorithm,which uses the measurement information from onboard GPS and onboard laser detector to acquire the target position,is proposed to obtain the accurate position of ground target in real time in the trajectory correction process of semi-active laser terminal correction projectile.A target localization model is established according to projectile position,attitude and line-of-sight angle.The effects of measurement errors of projectile position,attitude and line-of-sight angle on localization accuracy at different quadrant elevation angles are analyzed through Monte-Carlo simulation.The simulation results show that the measurement error of line-of-sight angle has the largest influence on the localization accuracy.The localization accuracy decreases with the increase in quadrant elevation angle.
