Abstract
With the widespread use of remote sensing images, low-resolution target detection in remote sensing images has become a hot research topic in the field of computer vision. In this paper, we propose a Target Detection on Super-Resolution Reconstruction (TDoSR) method to solve the problem of low target recognition rates in low-resolution remote sensing images under foggy conditions. The TDoSR method uses the Enhanced Super-Resolution Generative Adversarial Network (ESRGAN) to perform defogging and super-resolution reconstruction of foggy low-resolution remote sensing images. In the target detection part, the Rotation Equivariant Detector (ReDet) algorithm, which has a higher recognition rate at this stage, is used to identify and classify various types of targets. While a large number of experiments have been carried out on the remote sensing image dataset DOTA-v1.5, the results of this paper suggest that the proposed method achieves good results in the target detection of low-resolution foggy remote sensing images. The principal result of this paper demonstrates that the recognition rate of the TDoSR method increases by roughly 20% when compared with low-resolution foggy remote sensing images.

Summary
The task of target detection in remote sensing images is to locate, recognize, or classify ground objects. The task of single image super-resolution (SISR) [4] processing is to recover a high-resolution image from a low-resolution image. Before the deep learning method was proposed, the Bicubic [4] method was usually used to deal with the problem of single image super-resolution. This method only used the pixel information of the low-resolution image itself, and all the pixels at each position were interpolated based on the information around the corresponding pixels so that the super-resolution image obtained by this method was unsatisfactory and had poor image quality.
