THE QUICK IMAGE DISPLAY (QUID) MODEL

WE PROPOSE TO DELIVER A QUICK IMAGE DISPLAY MODEL FOR INFRARED TARGETS. THE PROPOSED MODEL WILL MAKE FULL UTILIZATION OF THE AVAILABLE HARDWARE ON THE IRIS GRAPHICS WORKSTATION. IT WILL BE DESIGNED SO THAT ITS PROCEDURES WILL BE DIRECTLY APPLICABLE TO THE HARDWARE UTILIZED BY THE SIX DEGREES OF FREEDOM FLIGHT SIMULATOR. IT WILL BE ACCURATE FOR RANGE STUDIES SINCE ALL EFFECTS OF ATMOSPHERIC PATH CHANGES WILL BE INCLUDED. IT WILL HAVE TWO OPTIONS FOR DIRECTIONAL EMITTANCE AND BIDIRECTIONAL REFLECTANCE. ONE OPTION WILL USE THE SSI MODEL THAT IS CURRENTLY IN SPIRITS AND IN SSTIRS. THE OTHER OPTION IS A NOVEL UTILIZATION OF THE WORKSTATION'S LIGHTING MODELS WHICH WILL YIELD A DIRECTIONAL EMISSIVITY AND A BRDF THAT SATISFIES ENERGY CONSERVATION. THE COMBINATION OF ACCURACY AND SPEED FOR ALL ASPECTS WILL MAKE THE MODEL A USEFUL TOOL FOR THE ANALYSIS OF TARGET DEGRADATION AS A FUNCTION OF RANGE. A PROTOTYPE MODEL WILL BE DELIVERED AT THE END OF PHASE I.
