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 main parameters of the optical system of ATP experiment system are as follows: beacon beam divergence angle: 2αb = 5mrad; optical receiving antenna field of view : 2βω = 10mrad; Search scan range: 2α≥ ± 1 °, 2β≥ ± 1 °; Installation Antenna error: ≤0.5 °. Experimental results are also validated at a distance of 1.6 km. The experimental results are in good agreement with the theoretical analysis.
