Through-The-Wall Radar Imaging With Wall Clutter Removal Via Riemannian Optimization On The Fixed-Rank Manifold

Hugo Brehier, Arnaud Breloy, Chengfang Ren, Guillaume Ginolhac

ICASSP 2024accepted

We introduce a new method for Through-the-Wall Radar Imaging (TWRI) that detects the location of stationary targets hidden by a wall. A crucial step is the mitigation of wall returns which obscure the scene and which are characterized by their low-rankedness given the radar measurement setup. Wherea…

Robust and Globally Sparse Pca via Majorization-Minimization and Variable Splitting

Hugo Brehier, Arnaud Breloy, Mohammed Nabil El Korso, Sandeep Kumar

ICASSP 2023accepted

This paper addresses the problem of robust and sparse PCA. We consider a formulation combining a M-estimation type robust subspace recovery term and a mixed norm that promotes structured sparsity in the basis vectors, which is especially interesting for joint dimension reduction and variable selecti…
