机载激光成像雷达运动畸变的分析与修正

针对在机载应用情况下,单元探测的激光成像雷达的载机运动对其地面目标成像影响的问题,给出了激光成像的系统模型;阐明了激光雷达扫描成像的映射变换关系,建立了定位于大地坐标的被成像目标与载机运动平台以及雷达坐标之间的数学关系式,分析了导致目标成像发生畸变的原因及影响因素,并给出了按时序的逐级修正方法。

Analysis and Amending of Dynamical Disto of Airborne Imaging Ladar

This paper studies airborne imaging ladar with unit detector to analyze the effects of the airborne movement on laser scanning imaging of ground target.In this paper, the imaging ladar system model is founded and the mapping transrormation relalionship of ladar scanning imaging are explained. The mathematic relations among imaged earthbased target and moveing airborne and Ladar are established.The distortion mechanism and factor are analysed.At last the method of time series level by level amending is deduce.
