Abstract
A LADAR system includes a detector optical arrangement defining a current optical field of view. An illumination subsystem without moving parts transmits pulsed illumination at different times to each of a number of illumination sub-regions of the current optical field of view, and a detection subsystem, including one or more detectors, detects reflected illumination from a corresponding one or more detection sub-region of the current optical field of view. Each of the detection sub-regions overlaps illumination sub-regions so that an overlap of each of the illumination sub-regions with the detection sub-region defines a LADAR image pixel of resolution finer than the detection sub-region.
