Abstract
Lidar reflective tomography imaging has been shown a technology to obtain high resolution image of remote object, and has great application value in the field of space object surveillance and identification. In this paper, the fundamental of lidar reflective tomography imaging is given, some key issues of ground-based lidar reflective tomography imaging of space object are analyzed: the long-range detection and high range resolution is obtained by using chirp transmit signals, the usefulness of these range data for use in reflective topographic reconstruction of space object image is discussed; atmospheric turbulence effects on the reflective tomography is analyzed, which shows that 10.6μm lidar reflective tomography is not sensitive to atmospheric turbulence under certain receiving aperture; in order to resolve the question of incomplete detection angles in space target reflective tomography, regularization method is applied, the homotopy parameter is adopted in order to fix the weight coefficient efficiently, accuracy of image reconstruction has been improved. At last, the simulation results of satellite model validate the feasibility of this technical scheme.
