针对自行高炮伺服系统发生故障、应急方式工作时存在反应速度慢、对准精度低、提前量误差大的问题, 提出采用动态观瞄装置产生含有光标的视频信号, 通过实时接收并解算目标或火炮提前量数据, 控制视频信号中光标的动态位置。该视频信号经微显示器显示并被投影到瞄准镜分划面上, 使动态光标出现在瞄准镜视场中, 应急工作时引导炮长手动使瞄准线和火炮快速调转、跟踪、迅速到达提前位置, 从而减轻操作难度, 提高调转速度, 提高命中概率。该装置随某型自行高炮试验, 实现预定功能、达到预定效果。

The servo system of the self-propelled anti-aircraft artillery has the possibility of failures. While working in the emergency state, it has the problems of slow reaction, low precision and large error for lead. To solve these problems, the dynamic cursor circuit was proposed to use for producing the video frequency with a dynamic cursor. Thus, the target data and the lead of artillery could be calculated in real time, so as to control the position of the dynamic cursor. The video frequency signal was shown on the display screen and projected to the reticle surface of the sight lens, enabling the dynamic cursor in the field of view. Therefore, it could guide the user to aim manually and to slew the artillery to the lead position rapidly while working in the emergency state. The use of the dynamic cursor in the sight lens could reduce the operational difficulty and improve the slew rate, facilitating to grasp the fighting chance and increase the probability of hitting. This device was tested with a type of self-propelled anti-aircraft artillery. The results show that it fulfills its intended functions and can attain the predetermined effect.
