Laboratory demonstration of static-mode down-looking synthetic aperture imaging ladar

【摘要】 A static-mode synthetic aperture imaging ladar(SAIL) in which the target and carrying platform are kept still during the collection process is proposed and demonstrated. A target point of 0.5 mm × 0.5 mm and a two-dimensional(2D) object are reconstructed in the experiments, in which an optical collimator with a focal length of10 m is used to simulate the far-field condition. The achieved imaging resolution is in agreement with the theoretical design. The static-mode down-looking SAIL has the capability to eliminate the influence from the atmospheric turbulence and can be conveniently operated outdoors.更多还原
