Abstract :
The diagnostic of the effective surface geometry of the reflector antenna is performed by exploiting only the amplitude of the radiated pattern. The approach is based on a convenient factorization of the aperture field and performs an optimal estimate of the reflector distortions by carefully choosing the output space and the space of the unknowns in order to improve the behaviour of the procedure with respect to the trapping problem.<>
