摘　　要：为了获取模拟月面的三维地形数据,采用激光雷达系统进行专项试验场地形测量。文章分析了激光雷达系统的测量站点布局规划和位置参数设置对大尺寸地形扫描测量的影响,重点研究了激光雷达在景深条件限制下为实现最大扫描面积的有效扫描高度和扫描宽度设置。研究结果可为深空大范围扫描测量深入研究提供一定的参考。In order to acquire the three-dimension topographical data of the simulated lunar surface,a laser radar system is used to measure the topography of the experimental area.To accomplish the large-size topography scanning,the layout of the laser radar＇s measurement sites and the setting of laser radar＇s location parameters are determined,focusing on the effective scan height and width of the laser radar for maximizing the scanning area within the limit of the depth of the field.

关 键 词：激光雷达 大尺寸地形扫描 模拟月面 景深
