A process for determining a correction function that makes it possible to compensate for the positioning errors of the radiating elements of a network antenna, the latter comprising N beams, characterised in that it comprises at least: - a first step of measuring the positioning error δ(n) of each of the N beams and compiling an imperfections vector I, the N components of which are the values δ(n) of the positioning error, - a second step of spectral decomposition of the error function δ(n) by applying a Fourier transform to the imperfections vector I, the spectral decomposition taking the form of a vector dd(i) defined by the relation: dd i = ∑ n = 1 N δ n. e − j.2. Π. i − 1. n − 1 N with i ∈ [1,N] - a third step of recomposing the error function δ(n) on the basis of the vector dd(i) obtained after the preceding step, this re-composition that restores the imperfections vector I being implemented by applying an inverse Fourier transform on the vector dd, each component δ(n) of the vector i being defined in the form of a sum of sinusoidal components E n (i) by the relation: δ n = 1 N x ∑ i = 1 N dd i. cos 2.
