In order to evaluate the performance of precision guided weapon using staring infrared imaging systems, using the method of reliable digital modeling and simulation has become an important solution and attracted worldwide attention. Due to plenty of measured data has been achieved during previous research and development, a method of staring infrared systems reconstruction based on measured data is researched in this paper, which is combined with ideal sensor of typical IR scene simulation platform and considering sampling, respond, noise and modulation transfer theory, etc. In addition, 3D-noise model and computer simulated image is used to validate the reconstruction's precision. Finally, in the view of comprehensive evaluation, sensitivity threshold as an example is measured in the laboratory, which revalidated this effective method. The study lays a foundation for staring infrared guided weapon's actual combat application.
