The retrieval of the faulty radiators in the antenna under test (AUT) is formulated within the compressive sensing (CS) framework and it is efficiently and effectively solved through a customized Bayesian CS (BCS) solver. Robust and reliable reconstructions of the AUT status are yielded by means of the proposed diagnosis tool also in presence of significant amounts of noise on processed far‐field data. Some numerical experiments are presented to assess the BCS‐based method when dealing with different operative conditions as well as considering a variation of the array size and failure rate. date: 2019 publisher: ELEDIA Research Center - University of Trento referencetext: [1] P.
