Abstract: 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.
