The copy of record is available at IET Digital Library -[Abstract] It is shown, by means of numerical simulation, that the Moore-Penrose pseudoinverse of a matrix taken from an overdetermined system can be applied to retrieve the excitation distribution of a planar array of parallel dipoles with faulty elements, by measuring the complex radiated field in its near zone. Failures on voltage (considering mutual coupling) and current of several elements, and systematic or random measurement errors, are considered in the simulation.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Antenna theoryDipole antenna arraysFailure analysisMatrix decompositionMeasurement errorsNumerical analysisPlanar antenna arraysjournal articleopen access10.1049/el:20056849
