摘　　要：在描述量子定位系统(QPS)及其捕获、跟踪和瞄准(ATP)系统的工作过程的基础上,对ATP中的精跟踪系统的组成结构进行了详细的设计,并对其中各部件参数与系统性能之间的关系进行分析;对精跟踪系统中的快速反射镜的镜面直径、转角范围、角分辨率、谐振频率、精跟踪探测器的像元尺寸、帧频、像元阵列、灵敏度等参数的合理选择进行详细分析;建立精跟踪控制系统各部分的传递函数及完整方框图;对超前瞄准系统结构以及超前瞄准角与超前瞄准探测器中超前瞄准点的坐标转换关系进行了分析,为超前瞄准角闭环实现提供了一套实施方案。Based on the work process of quantum positioning system （ QPS） and its acquisi（ATP ） system, the structure of the fine tracking system in ATP is designed. The relationships between the parameters ofeach component and the system performance are analyzed. In the fine tracking system, the reasonable selections of the pa-rameters are analyzed in detail , such as the mirror diameter , the angle range , the angular resolution , the resonant frequency of the fast steering mirror , the pixel size , the frame rate , the pixel array and the sensitivity of the fine tracking sensor. The complete block diagram of the fine tracking control system and the transfer function of each part are established. The struc-ture of the advanced targeting system , the coordinate transformation relationship between the advanced tathe advanced targeting point in the advanced targeting sensor are analyzed.
