摘　　要：为解决某型捷联激光导引头轴向标定测角误差大的问题,研究如何使用现有设备进行测角精度更高的网格化标定。采用逐点极坐标转换的方法获取网格化标定点的转台运动坐标,项目得以实施。在研究过程中,解决了网格化标定时因转台重复往返运动以及转台需要多次进行归零操作而导致网格化标定消耗时间太长问题。最终顺利将该型激光导引头网格化标定落实于实物并应用于生产,大幅提高了该型激光导引头的制导精度。To reducing the error of a strapdown laser seeker angle output,a new angle calibration method should be applied on the existing equipment.By using coordinate transformation,the target could be reached.However,the time consumption of new calibration is too long.This is because of the turntable having too many times to-and-fro movement and reset operation.Through reordering the angle calibra⁃tion,the problems were solved.Finally,the gridding angle calibration of this laser seeker is successfully applied in the production,and it greatly improves the guidance precision of this laser weapon.
