Abstract:
1. A process of compensating for the effects of the errors of location of the radiating elements of an array antenna on the radiation pattern of said antenna, said process comprising the following steps: measuring the positioning error for each radiating element n and compiling an imperfection vector I, whose components are values of the positioning error function δ(n); computing a spectral decomposition of the positioning error function δ(n), in the spatial domain, in the form of the sum of spectral sinusoidal components dd(i) calculated by application of a Fourier transform to the imperfections vector I, and applying an inverse Fourier transform to vector dd obtained in this way, each component of vector I being then expressed as a sum of sinusoidal errors; calculating correcting functions Δ elaborating a correction function Δ(n) from Δ
