description: The object of the study â speckle noise on radar images. The aim of this work â to develop a method for removing speckle noise from radar images using deep learning. The paper investigates the prospects of a neural network approach to speckle noise filtering on radar images. A fully convolutional neural network that removes speckle noise from images with a quality superior to filters that do not use machine learning is created and trained. We compared the quality of noise removal using the obtained neural network and other filters: the median filter, the Lee filter, the Frost filter, the Kuan filter, the bilateral filter, the FastNL filter. It is shown that on real radar images the filter based on the fully convolutional neural network surpasses the other considered filters by the degree ofsimilarity of the filtered image to the original image before the speckle-noise overlay. The resulting neural network can be used in practice to filter speckle noise on radar images.
