LARGE AREA FAST SPECTRORADIOMETER

THE U.S. NAVY AND MARINE CORPS HAS IDENTIFIED THE NEED FOR A FAST FIEL6L-PORTABLE SPECTRORADIOMETER. THIS CAPABILITY WILL ALLOW MARINE CORPS AND NAVY PERSONNEL TO DETECT TARGETS IN A CLUTTERED BACKGROUND.THE TARGETS CAN RANGE FROM MINES TO TANKS AND ROCKET LAUNCHERS. THE BACKGROUNDS CAN RANGE FROM ROCKS AND SMALL BUSHES THAT CLUTTER MINEFIELD SCENES TO DENSE FOLIAGE THAT CONCEAL LARC;E VEHIELSE. MULTISPECTRAL SCENE ANALYSIS CAN BE USED TO DETECT TARGETS IN CAMOUFLAT;ED OR CONCEALED BACKGROUNDS. TO MEET THIS APPLICATION, A DESIGN CAPABLE OF ACQUIRING 256 SPECTRAL BANDS OVER A 375 BY 500 PIXEL AREA IS PROPOSED. A BUILT-IN COINPUTER AND DIGITAL SIGNAL PROCESSOR WILL PERFORM RADIOMETRIC CORRECTIONS, BINNING., BAND RATIOING, AND IMAGE PROCESSING TASKS. AN INNOVATIVE DESIGN THAT COMBINES HIGH THROUGHPUT, IMAGING, HOLOGRAPH.LC GRATINGS WITH HIGH FRAME RATE OCD-S, A FRAMING MIRROR, STATE-OF-THE-ART DIGITAL SIGNAL PROCESSORS, FLAT PANEL DISPLAYS, AND LARGE CAPACITY DIGITAL RECORD.ERS IS PROPOSED FOR THE LARGE AREA, FAST SPECTRORADIOMETER. THE INSTRUMENT WILL GIVE MARINE CORPS AND NAVY PERSONNEL A FIELD PORTABLE INSTRUMENT THAT CAN IMAGE A MULTI-SPECTRAL SCENE IN LESS THAN 0.25 SEC AND PROCESS AND DISPLAY THE DATA IN 20-30 SECONDS.
