Undersampled imager performance enhancement has been demonstrated using super-resolution reconstruction techniques. In these techniques, the optical flow of the scene or the relative sub-pixel shift between frames is calculated and a high-resolution grid is populated with spatial data based on scene motion. Increases in performance have been demonstrated for observers viewing static images obtained from super-resolving a sequence of frames in a dynamic scene and for dynamic framing sensors. In this paper, we provide explicit guidance on how to model super-resolution reconstruction algorithms within existing thermal analysis models such as NVThermIP. The guidance in this paper will be restricted to static target/background scenarios. Background is given on the interaction of sensitivity and resolution in the context of a super-resolution process and how to relate these characteristics to parameters within the model. We then show results from representative algorithms modeled with NVThermIP. General guidelines for analyzing the effects of super-resolution in models are then presented.
