The validation of models in an imaging infrared simulation

Simulation models must be validated to ensure that the simulation reflects reality. The approach taken here is based on a well accepted framework that considers reality, the conceptual model and the computer model. The paper shows how these principles are applied to models in the infrared simulation and how the results are interpreted. The concepts discussed here are not bound to infrared systems, and can be applied to radar, in the environmental sciences and even in the human sciences.
