空间交会对接激光雷达合作目标设计

Design of Lidar Cooperative Target for Space Rendezvous and Docking

空间交会对接激光雷达技术对于我国的太空事业发展具有重要的意义，合作目标是交会对接雷达的重要组成部分。本文介绍了国内外交会对接激光雷达合作目标的发展现状。根据任务特点，从合作目标布局，有效面积、构型设计等方面入手，重点分析了不同切割方式下角反射器有效面积和入射角的关系，并提出一种有效截面的计算方法。我们设计的激光雷达合作目标已经成功地应用于我国首次太空交会对接任务。

Space rendezvous and docking technology plays an important role in the development of our country＇s space field activities, and the cooperative target is an essential component of space rendezvous and docking lidar system. In this paper, we systematically introduced the development of lidar cooperative target for space rendez- vous and docking. According to the task requirement, we discussed the key technologies of the cooperative target including layout, effective area with the emphasis on the relationship between effective area of corner reflector and laser incident angle under different cutting conditions. We also proposed a new method for calculating lidar effective aera. The cooperative target we designed has been successfully applied to our eountry~ first space ren- dezvous and docking task.
