Abstract
A laser is used to emit a diverging laser flash configured to illuminate a detection zone. A pseudoimaging optical receiver system is used to detect reflections from objects in the detection zone. The receiver system includes a time-gated photodetector array that is used to record signatures in a voxel array. A voxel processing module receives the voxel array and detects a reference clutter signal within the array. Potential targets are then detected according to target signals in relation to the reference clutter signal.
