Abstract
A dynamic model of infrared missile engagements needs to integrate the output of signature models into a scene of given resolution with a changing viewpoint and moving targets against some background. Some signature prediction models are stand-alone software packages which currently cannot be dynamically interfaced to a running engagement model. They can be used to conveniently provide an image of an infrared target at high resolution at a single viewpoint. Using an imaging radiometer model, high-resolution, high-fidelity signatures can be quickly combined into a scene of desired configuration. This paper presents the derivation of such a model from physical and signal processing considerations, and its practical implementation. The derived methodology provides very high radiometric accuracy with a rigorously controlled error and smooth integration of objects moving through the scene.
