根据机载地面测绘对地面分辨力的需要，首先给出了机载扫描激光测距的地面采样点分布的两种轨迹形式，然后着重分析了直线形式扫描轨迹的地面采样点特征以及水平分辨力与有关影响因素之间的关系，并给出地面水平分辨力受波束倾角、扫描速度、激光脉冲重复率、飞行高度、飞行进度等影响，在不影响作业效率的情况下，提高水平分辨力最有效的途径是提高激光脉冲重复率。最后讨论了改善地面水平分辨力的途径，得到了相关结论。
According to the need of on-the-ground surface mapping for the resolution of ground, firstly, two kinds of track patterns of ground sampling point distribution of airborne scanning laser ranging are given. Then, the features of ground sampling points and the horizontal resolution of linear scanning trajectory are emphatically analyzed. And the related factors, and gives the horizontal resolution of the ground by the beam tilt, scanning speed, laser pulse repetition rate, flight altitude, flight progress, etc., without affecting the operating efficiency of the case to improve the horizontal resolution The effective way is to improve the laser pulse repetition rate. Finally, the ways to improve the horizontal resolution of the ground are discussed, and the relevant conclusions are obtained.
