Abstract

A method for determining an estimate of a radiation pattern of a phased array antenna formed by a number M of radiating elements (8,10), including the steps of: determining a theoretical function (PT) establishing a first M-tuple of phase shifts (α11,... αM1) related to the M radiating elements; determining a plurality of theoretic electromagnetic field values on the basis of the theoretical function; controlling the radiating elements so as to introduce phase shifts equal to the phase shifts of the first M-tuple, and subsequently determining a plurality of electromagnetic field measures; determining an error vector (Err1), as a function of the plurality of theoretical values and of the plurality of measures. The method further includes the steps of determining an approximating function, on the basis of the error vector and of the first M-tuple of phase shifts, and determining, for a generic M-tuple of phase shifts to be characterized (α1x, αMx), an estimate of an electromagnetic field irradiated by the antenna, on the basis of the approximating function and of the theoretical function.
