US Patent:

56822251, Oct 28, 1997

Filed:

Jun 7, 1996

Appl. No.:

8/664231

Inventors:

David S. DuBois - Arlington TX
Bruno J. Evans - Arlington TX
Gary K. Jenkins - Arlington TX

Assignee:

Loral Vought Systems Corp. - Grand Prairie TX

International Classification:

G01N 2100

US Classification:

356 73

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.

US Classification:

Abstract:

A sensor assembly for imaging passive infrared (IR) scenes and active laser radar (LADAR) scenes and for generating multi-dimension image data sets, and a method for same. A two-dimensional semiconductor imager sensitive to both passive IR radiation and active LADAR radiation when used in conjunction with subsequent signal processing creates a two-dimension passive image data set and a three-dimension active image data set with common x and y coordinates. The passive image data set is collected substantially proximate in time with the active image data set. The two image data sets are combined to form a multi-dimension image data set with the surface of three-dimensional objects indicating heat emission. The sensor assembly applies to burst illumination LADARs operating at a variety of wavelengths and passive IR detection in the middle wavelength IR (MWIR) or long wavelength IR (LWIR).

Abstract:

A visual recognition system is disclosed for detecting a target within a scene. A LADAR system and method is employed for scanning laser light signals across a scene having a target to be characterized. Laser light reflected from the target is detected and processed into a three-dimensional image. The three-dimensional image is segmented to separate the target from the overall scene. Substantially, only the segmented target data is either displayed locally or transmitted via a narrow bandwidth transmission medium to a remote site for display. The invention finds particular application in military situations where enemy armor is detected and the segmented version of the armor is transmitted via SINCGARS.
