摘　　要：对目标的捕获、跟踪和瞄准（Ａｃｑｕｉｓｉｔｉｏｎ，Ｔｒａｃｋｉｎｇ，Ｐｏｉｎｔｉｎｇ－ＡＴＰ）技术进行了理论分析和实验研究，ＡＴＰ实验系统光路的主要参数为：信标光束散角：２αｂ＝５ｍｒａｄ；光接收天线视场：２βω＝１０ｍｒａｄ；搜索扫描范围：２α≥±１°，２β≥±１°；安装天线误差：≤０．５°。并在１．６ｋｍ距离上进行了实验验证，实验结果与理论分析基本一致。The Acquisition, Tracking and Pointing (ATP) technology is one of the key technologies in the free space laser communications system. This paper analyzes the ATP theory, and obtained results from experiment. The key parameters of the experimental system are: (1) beacon divergence, 2α b=5 mrad; (2) receiver field of view, 2β ω=10 mrad; (3) angular coverage, 2α≥±1°, 2β≥±1°. The results of the experimental demonstration show that the system can work well in the distances of 1.6～5.0 km. The results accurately match the theoretical analysis.
