ABSTRACT:
A method and apparatus for generating sharper and more accurate LADAR intensity images is disclosed. The LADAR system includes an optical transmitter and receiver that generates and scans a laser beam in a target field. A backscatter detector senses the magnitude of the generated laser beam. A signal processing unit uses the magnitude of the transmitted laser beam to adjust the magnitude of received reflections to produce a sharper intensity image.
