Abstract
To help system designers to evaluate the performances of a 128 * 128 cooled IRFPA, a behavioral model has been realized. It simulates the characteristics of the component in term of temporal and fixed pattern noise. This model was designed to be incorporated in a complete simulation of an optronic system including IR scene generation, optics modeling, post-treatment and corrections of the simulated video signal delivered by the detector. By this way, costs and duration of system evaluation for different kinds of scenario were strongly reduced. The architecture of the model was based on electrical simulations of the circuit. Its parameters were fitted with measurements on a real IRCMOS demonstrator in order to reflect with precision its behavior. In this paper we present the architecture of the IRFPA model. Comparisons between modeling and measurements are also presented exhibiting a real good agreement in term of video signal uniformity and noise. This demonstrates the advantages of this modeling approach for optronic system evaluations.
