Abstract
An airborne imaging lidar (light detection and ranging) sensor is provided which employs multiple pulsed laser transmitters, multiple gated and intensified array camera receivers, an optical scanner for increased field of regard, and a computer for system control, automatic target detection and display generation. The laser transmitters and multiple camera receivers are optically boresighted to the optical scanner (e.g., oscillating flat mirror) for an increased swath width perpendicular to the aircraft heading. The several laser transmitters are coupled for increased power and system sensitivity.
