Towards this end, an innovative Bayesian compressive sensing (BCS) methodology is derived and implemented in order to combine the well-known regularization capabilities of CS solvers with the progressively acquired information about the imaged scenario through the iterative multi-scaling approach (IMSA). Selected numerical results are presented in order to verify the effectiveness of the proposed IMSA-BCS technique, as well as to compare it against competitive state-of-the-art approaches.
