Plug-and-Play Regularization on Magnitude with Deep Priors for 3D Near-Field MIMO Imaging

arXiv:2312.16024v2 Announce Type: replace-cross
Abstract: Near-field radar imaging systems are used in a wide range of applications such as concealed weapon detection and medical diagnosis. In this paper, we consider the problem of reconstructing the three-dimensional (3D) complex-valued reflectivity distribution of the near-field scene by enforcing regularization on its magnitude. We solve this inverse problem by using the alternating direction method of multipliers (ADMM) framework. For this, we provide a general expression for the proximal mapping associated with such regularization …
