Abstract

The work aims to propose a prediction method for the operating distance of an infrared imaging system based on measured parameters, so as to solve the technical challenges in evaluating the performance of infrared imaging systems in complex battlefield environments and provide crucial data support for combat applications.The prediction method for the operating distance of the infrared imaging system in complex environments based on measured parameters was studied, the quantitative analysis of the target characteristics and environmental parameters was carried out, the estimation method for the operating distance of the infrared imaging system based on the measured minimum resolvable temperature differencecurve and the attenuation of the target-background temperature difference was proposed and the accuracy of the estimation model was evaluated. Through an analysis combined with the measured results, the coupled effects of different target characteristics and environmental parameters on the observation distance were discussed, and an evaluation method for the effect of the operating distance under different target and environmental parameter conditions was established. Experiments showed that, compared with the measured data, the relative error of the target operating distance found by the method proposed here was less than 6.5%, and the relative error of the target recognition operating distance was less than 10%. The model studied in this work has a high degree of accuracy and can be effectively used to evaluate the operating distance of the infrared imaging system under non-typical environmental conditions.
