Multiple target tracker and liquid crystal waveguide (LCWG) beam steerer for designation, range finding and active imaging

摘要

A multiple target tracker and beam steerer utilizes liquid crystal waveguide (LCWG) beam steering to illuminate multiple tracked targets per frame one target at a time for designation, range finding or active imaging. The steering rate and range afforded by the LCWG supports various tracker configurations (out-of-band, in-band or dual-band video cameras), LADAR detectors (single pixel or pixelated) and prioritization of tracked targets to vary the revisit rate or dwell time for an illuminated target. A user interface accepts commands from an operator to select the targeting mode, control cue-box size and position within the FOV and target selection.
