INFRARED BACKGROUND/CLUTTER/TARGET SIGNATURE MODEL

THIS PROPOSAL RESPONS TO THE NEED FOR A PC-BASED SCENE GENERATOR CODE WITH SUFFICIENT ACCURACY FOR PREDICTION OF FIELD INSTRUMENTATION PERFORMANCE. THE STARTING POINT FOR THE PHASE I EFFORT IS THE IRVING MODEL, A MULTI-FACETED TARGET AND BACKGROUND IR IMAGING CODE DEVELOPED BY THE NAVAL WEAPONS CENTER. IRVING CALCULATES INFRARED SCENE RADIANCES INCLUDING TARGET AND CLUTTER EFFECTS. TO ENHANCE THE APPLICABILITY OF THE MODEL TONAVAL SURFACE WARFARE SCENARIOS, AN IMPROVED FINITE CLOUD MODEL AND AN OCEAN SURFACE MODEL WILL BE INCORPORATED INTO IRVING DURING PHASE I. SUBSEQUENTLY, IRVING PREDICTIONS WILL BE TESTED AGAINST EXPERIMENTAL DATA AND A PREVIOUSLY VALIDATED TARGET CODE TO EVALUATE MODEL PERFORMANCE. BASED ON THESE STUDIES, UPGRADES NECESSARY TO MEET SYSTEM PERFORMANCE TESTING STANDARDS WILL BE RECOMMENDED. THE IMPROVED IRVING MODEL RESULTING FROM THE PHASE I EFFORT WILL FORM THE BASIS FOR SUBSEQUENT UPGRADES DURING PHASE II, ESPECIALLY IN THE AREA OF CLUTTER.
