DUAL BAND INFRARED DISCRIMINATION TECHNIQUES

I-MATH AND OUR SUBCONTRACTOR, QUEST RESEARCH CORPORATION, HAVE PROPOSED AN APPROACH FOR DETERMINING THE OPTIMAL SUB-BANDS WITHIN THE 3-5 AND 8-12 MICROMETERS REGIONS WHICH IS BASED ON A METHODOLOGY KNOWN AS DIFFERENTIAL IRRADIANCE. THIS TECHNIQUE IS PART OF A PATENT DISCLOSURE AUTHORED BY QUEST AND NRL WHILE PERFORMING ON OPTIMAL DUAL BAND SELECTION FOR A NRL IR SYSTEM. THIS TECHNIQUE RESULTED IN DEMONSTRATED PERFORMANCE IMPROVEMENTS WHICH ALLOW THRESHOLDS FROM 10 TO 70 TIMES LOWER THAN TRADITIONAL METHODS FOR COLOR DISCRIMINATION. I-MATH WILL DESIGN AND IMPLEMENT THE REQUIRED SIGNAL PROCESSING ALGORITHMS. DUAL MODE DISCRIMINATION PERFORMANCE IN AN OPERATIONAL ENVIRONMENT WILL BE EVALUATED BY I-MATH USING THE ELECTRO-OPTICAL SENSOR SIMULATION (EOSSIM) MODEL., A PC BASED, IMPROVED VERSION OF THE INFRARED SEARCH AND TRACK EVALUATION MODEL (IRSTEM).
