A situation awareness sensor includes a plurality of N sensor channels, each channel including an optical phased array (OPA) having a plurality of solid-state laser emitters, a command circuit and a detector. The command circuit controls the relative phase between the laser emitters to command a divergence, shape and exit angle of a spot-beam to scan a channel field-of-view (FOV). The OPAs may be controlled individually or in combination to command one or more spot-beams to scan an aggregate sensor FOV and to track one or more objects.
