Using systemic non linearity statement and analysis,a new IRFPA nonuniformities correction algorithm is developed from the principle of correction algorithms based on IR reference emitter.Each detector unit is treated as a non linear system according to the algorithm,from which the principle is valid for nonuniformities correction algorithms based either on scene moving analysis with certain conditions or on IR reference emitter,it can adapt to the nonuniformities change slowly with time and with external conditions and is really a adaptive algorithm.
