| 摘 要： | 火箭制导系统中惯性器件的方位敏感轴方向通常是借助于直角棱镜来确定的,因而直角棱镜的棱脊倾斜对方位瞄准精度有影响.本文推导了直角棱镜的棱脊倾斜造成的反射光矢量的精确表达式,并在此基础上讨论了棱脊倾斜对线阵CCD测角的影响.

| Abstract: | The direction of the sensitive axis in the inertial guidance platform is determined by the right-angle prism,so the accruacy of the azimuth aiming must be influenced by the prism tilting.In this paper,the whole formula for the reflected ray vector of the right-angle prism is derived,based on it,the influences of the prism tilting on azimuth laying are discussed. |
