基于PSD的弹道修正弹初始对准方法研究

Research of Initial Alignment for Trajectory Correction Projectile Based on PSD

弹道修正炮弹在进行导航控制之前.需要装定初始导航数据。本文基于双矢量确定姿态的一般原理,利用 PSD 光学敏感器系统测量弹丸飞行姿态,推导出载体坐标系和导航坐标系之间的转换矩阵。仿真结果表明,利用这种方法实现的初始对准过程速度快,能够有效地解决弹道修正弹的初始对准问题。

Initial navigation data should be set before navigation and control of trajectory correction projectile.Based on the theory of two vectors,attitude angle is measured by PSD(position sensitive sensor).From this the conversion ma- trix between body and navigation coordinate is obtained.Results from simulation show this method can solve the initial alignment in trajectory correction projectile effectively.
