Abstract Firstly, a method of infrared scene generation and correction was proposed in this paper, and a transformation model and a correction model of infrared scene were established based on the measured data obtained in the test range. Secondly, the measured data were transformed into the driving image of the scene simulator by the transformation model, and the driving image was iteratively corrected through the correction model, so that the simulated scene, which was projected by the scene simulator with the driving image as its input, was highly consistent with the test range scene corresponding to the measured data. Finally, the similarity evaluation between the simulated scene and the measured scene was carried out based on the sensitive features of the seeker. The conclusion showed that the transformation model and correction model had an efficient use of the measured data, eliminated the complex process of the target characteristics modeling and scene rending in the infrared imaging simulation, and provided a feasible approach to simulating the infrared scene with the same radiation characteristics as the test range.
