| Abstract: | In this paper, theproblem of dynamical distortion for airborne imaging ladar are analyzed and studied withcomputer simulation. The mechanism of distortion of Ladar target imaging following the sixfreedom move of the airborne are analyzed systematically. Every freedom move of theairborne lead up to distinct distortion are simulated and analyzed separately. This paperpresents the results of simulation analysis of imaging distortion for 2D plane targets and3D earth-based target. These figurative results describe audio-visualy distinctdistortion. The simulation results of dynamical distortion are very useful and worthful,which provide scientific basis for studing the amending necessity and determining thecorrection in various real application of imaging ladar. |
