摘要
针对激光成像雷达动态畸变问题，分析了雷达的目标成像；根据雷达载体六个自由度的运动产生畸变的机理，分别对机体每个自由度的运动引起的畸变进行了仿真研究，给出了二维平面目标或三维地面目标成像失真的仿真分析结果，这些结果对各种类型畸变给出了形象直观的描述。研究畸变的仿真软件对各种应用背景的激光成像雷达。
In this paper,the problem of dynamical distortion for airborne imaging ladar are analyzed and studied with computer simulation. The mechanism of distortion of Ladar target imaging following the six freedom move of the airborne are analyzed systematically. Every freedom move of the airborne lead up to distinct distortion are simulated and analyzed separately. This paper presents the results of simulation analysis of imaging distortion for 2D plane targets and 3D earth based target. These figurative results describe audio visualy distinct distortion. The simulation results of dynamical distortion are very useful and worthful, which provide scientific basis for studing the amending necessity and determining the correction in various real application of imaging ladar.
