摘要: 为解决大惯量光电跟踪器对高速机动目标的角秒级跟踪问题，设计了以快速控制反射镜作为精级，大惯量跟踪架作为粗级的双探测器型光电复合轴跟踪系统，并对快速控制反射镜和复合轴系统所涉及关键技术进行了分析。通过某模拟航路半实物跟踪试验不超过70rad的跟踪误差，验证了系统设计的有效性。Abstract: In order to accurately track highly dynamic targets with a heavy electro-optical tracking system, a coarse and fine axes driven servo system is presented, in which a fast steering mirror is used as fine control axis and conventional gimbals are used as coarse control axes. Some key technologies were discussed. Hardware-in-the-loop simulation indicates that a tacking error of less than 70rad is obtained, and the feasibility of the system is validated.
