Current infrared image super-resolution reconstruction methods, which are primarily designed based on experimental data, often fail in complex degradation scenarios encountered in real-world environments. To address this challenge, this paper presents a novel deep learning-based approach tailored for the superresolution reconstruction of infrared images in real scenarios. The significant contributions of this research include the development of a model that simulates infrared image degradation in real-life settings and a network structure that integrates channel attention with dense connections. This structure enhances feature extraction and image reconstruction capabilities, effectively increasing the spatial resolution of low-resolution infrared images in realistic scenarios. The effectiveness and superiority of the proposed approach for processing infrared images in real-world contexts are demonstrated through a series of ablation studies and comparative experiments with existing super-resolution methods. The experimental results indicate that this method produces sharper edges and effectively eliminates noise and blur, thereby significantly improving the visual quality of the images.
