The technical progress and present situations on Laser Coherent Imaging Radar(LCIR)were summarized. Technical frame structure and imaging results of two kinds of typical novel LCIR such as the Laser Range-Resolved Doppler Imaging radar (LRRDI)and Synthetic Aperture Laser radar (SAL) were discussed according to the general principle of LCIR. Some key technologies Should be solved in the course of engineering applications and laser coherent imaging were analyzed. The methods to solve the problems were put forward. The purpose was to provide reference studying LCIR on detecting targets for ground base, space and air borne.
