Description :

SAR (Synthetic Aperture Radar) images have the advantage of being
acquired at any time (day or night and whatever the weather conditions).
However, they are very noisy because of the speckle noise due to
coherent imaging. The acquisition of several images and their
combination allows to reduce very efficiently the noise present on the

Travail demandé : The aim of this project is to train a deep neural network to
simultaneously denoise multiple images in a MIMO framework (Multiple
Input Multiple Output). The training will be done in a self-supervised
way using the paradigm and architecture proposed in [1]. A comparison
with the Multiple Input Single Output framework developed in [2] will be
