On the Development of Synthetic Aperture Ladar Imaging

A brief overview on the development of Synthetic Aperture Ladar (SAL) imaging both domestically and abroad is introduced, where the quality of the obtained SAL image, the system architecture adopted and the overall progress on SAL development are reviewed. We suggest that a practical SAL should have proper imaging field of view and can be kind of adaptive to atmospheric turbulence so as to be accepted by possible end-users. We also urge that more outdoor SAL imaging experiments should be carried out and more imaging results should be published for the further development of SAL
