基于光电位置传感的弹道偏航与姿态测量

摘要

针对传统激光驾束制导弹道偏航和姿态测量需要高精度的惯性测量组件,存在系统复杂、体积大、成本高的问题,提出基于光电位置传感的弹道偏航与姿态角测量方法.该方法利用光电位置传感器PSD代替传统光电编码传感器完成弹道偏差测量,光电位置传感器还根据激光光斑在光电位置传感器上的位置代替传统惯性测量组件判断偏航角、俯仰角.同时实现弹丸弹道偏航与姿态角测量.测量精度评价分析表明,所提出的测量方法对弹丸偏航角和俯仰角测量精度可达到0.60°,能够满足小口径枪榴弹弹道修正的应用需求.%In view of the large volume,high cost and complexity of the traditional laser beam riding guidance trajectory and yaw attitude measurement to inertial measurement unit,a ballistic yaw and attitude angle measure-ment method based on PSD was put forward.The method of using PSD instead of traditional photoelectric coding sensor could complete ballistic measurement deviation,the location of the laser spot based on PSD replaced the traditional inertial measurement component judgment yaw angle and pitching Angle.At the same time,the measurement of projectile trajectory and attitude angle was realized.The measurement accuracy evaluation anal-ysis showed that the proposed method of measuring projectile yaw angle and pitching angle measurement accura-cy could reach 0.60°,which meet the application requirements of small caliber grenade trajectory correction.
