基于大地直角坐标系的瞄星法的研究

Research on method of aiming at stars based on ground rectangular coordinate system

系统零位一致性是舰载武器系统精确打击目标的基础。通常采用瞄星法进行系统零位中的角度电气零位一致性对准。传统的基于舰艇甲板直角坐标系的瞄星法在精度方面受船体甲板平面形变及设备水平度调整精度不高等因素影响较大。本文提出了基于大地直角坐标系的瞄星法,能较好地解决传统瞄星法存在的问题,提高舰载武器系统零位对准精度。

The consistency of system zero is the basis for Shipborne weapon systems in attacking tar- gets accurately. The method of aiming at stars is mostly used to adjust the angle electrical zero in the system zero. The conventional methods of aiming at stars based on the deck rectangular coordinate system are greatly affected in precision by such factors as the deck distortion and the low-precision leveling. The method of aiming at stars based on the ground rectangular coordinate system can solve these problems preferably and increase the precision of zero alignment of shipborne weapon systems.
