Research on modeling methods of infrared radiation characteristics of sea surface targets

Aiming at the urgent need of infrared radiation characteristics of different types of targets of interest under typical sea conditions in the development of high-precision missile infrared imaging guidance weapons, a model data-driven infrared radiation modeling method was developed. Firstly, by studying the influence factors of the system's full link in the Marine environment, the atmospheric radiative transfer model is constructed, and the theoretical values of the target and background parameters are calculated. Secondly, through the consistency comparison between the measured results and the theoretical model, the simulation target model is iterated to improve the system accuracy. Finally, the measured radiation luminance data of different bands and the theoretical modeling data of the same ship target in head-on and side-head-on attitude are compared and analyzed. The results show that the model prediction is in good agreement with the measured results, and the error is less than 15%. The proposed model is reliable and feasible, which can lay a model foundation for the follow-up development of infrared imaging guidelines, and provide technical support for the detection and recognition of sea surface targets.
