In this paper a novel and more realistic analytical model for the fixed-pattern noise present in infrared focal plane arrays is developed. The model captures, in the frequency domain, the spatial structure of the fixed-pattern noise yielding a suitable input/output representation for an infrared focal plane array. The theoretical and practical applicability the model is illustrated by both synthesizing fixed-pattern noise from three different infrared cameras and improving the performance of a previously reported fixed-pattern noise compensation algorithm.
