Targets and Backgrounds X: Characterization and Representation.
Modeling of material reflectance in simulated infrared/electro-optical scenes is typically done assuming a Gaussian distribution or similar simple statistical model, because of limited available measured data. Such an approach fails to capture the tr

High-Fidelity Simulation for Training, Test Support, Mission Rehearsal, and Civilian Applications.
The Georgia Tech Research Institute has for more than fifteen years developed and used digital scene models for IR simulation applications. Initially focusing on synthetic scenes of small extent but very high resolution (less than one meter), more re

Geographic background models constitute an important component in scene simulations as they provide one component of clutter observed through IR sensors. Accurate modeling of the spatially-varying features and signatures of the background presents a

An ocean surface model for synthetic IR/visible imaging applications has been developed at GTRI based upon the Pierson-Moskowitz wave spectrum. The model calculates a 2D grid of height values describing a given snapshot of the sea surface. This surfa
