为了探索一种炮长镜瞄准线间接稳瞄技术,分析了传统车载炮长镜直接稳定控制的优缺点。在此基础上提出了基于车载惯性导航设备的炮长镜间接稳定方法。将车载惯性导航设备输出的车体姿态信息通过坐标转换得到炮长镜的扰动速率信息并送给瞄准线控制单元,控制炮长镜瞄准线相对惯性空间保持稳定。对车载炮长镜间接稳定技术的稳瞄性能进行了实验验证,实验结果表明该方法是正确与实用的,与直接稳定方法相比达到了同样的稳瞄精度。

In order to explore an indirect line-of-sight stabilization technology of vehicular gunner's periscopic sight, advantages and disadvantages of traditional direct stabilization method were analyzed. On the basis of this, a method of indirect LOS stabilization based on inertial navigation equipment was proposed. From the output of inertial navigation equipment on land vehicle, the attitude information of vehicle could be achieved, and the disturbance information of gunner's periscopic sight was obtained by coordinate transformation from the attitude information. Then the disturbance information was sent to LOS control unit to keep the LOS be relatively stable to the inertial space. Experiments were taken to validate indirect LOS stabilization ability of vehicular gunner's periscopic sight. The experiments results show that the method is correct and practical, and has the same precision with the direct LOS stabilization method.
