一种运载火箭双光束地面瞄准的方法

Double Beam Aiming Scheme Applied to Launch Vehicle

提出一种用于运载火箭的双光束瞄准方法,两束代表方位基准的光束同时发射到悬挂在火箭瞄准窗口的自动准直仪上,自动准直仪通过光电接收获得基准方位,通过与惯组棱镜光电准直,测量出惯组棱镜法线与基准方位之间的夹角。该方法具有快速、测角敏区大等优点,研究结果可供未来运载火箭或导弹瞄准系统参考。

This paper introduces an efficient double beam aiming scheme applied to a launch vehicle. The auto-collimating theodolite fixed on the launch vehicle is illuminated by two reference beams and its basic position can be calculated by the offset of the focus on the photoelectric sensor. The angle between the normal of the inertial sensor assembly prism and the basic position is obtained by collimating the auto-collimating theodolite to the inertial sensor assembly. This scheme has advantages of fast and large aiming area that can be used on the aiming systems of launch vehicle and missile in the future.
