摘　　要：本文介绍了高帧频电视跟踪器的原理及单元电路,提出了一种快速求目标重心的方法。目标重心位置与系统复合光轴的误差脱靶量在场扫描结束后0.1ms的时间内实时输出,采用此跟踪器后.子系统的跟踪精度在最大加速度为20’/s^2最大速度为20’/s时可达到20”～30”。本文的最后给出了实验结果。In this paper, a high frame frequence TV tracker is introduced. A new method, calculation of the gravity centre for a target and a compatible method with standard TV monitor for high frame frequence image display, are presented. In this system, the deviation between the position of object and the main optical axis of the TV tracker can be outputed in real-time with only time delay of 0. 1ms after end of frame scan. The bandwith of the TV tracker is 25HZ. The tracking error of a complex axis servo system using this TV tracker has been achieved 20 - 30' under the maximum vilocity of 20/s and the maximum acceleration of 20/s2. The results of experiment are presented in the last paragraph of this paper.
