Abstract
A new aperture-like expansion of the field scattered by a reflector antenna is considered which allows the field radiated by such an antenna to be reconstructed starting from a limited number of computed values, essentially one per lobe. These values, in turn, are exact Fourier transforms evaluated at the Nyquist rate, which allows an optimal use of the Fast Fourier Transform algorithm. The results of an extensive numerical analysis are presented and briefly discussed. These results show the excellent performance of the proposed method, a very appealing one from the point of view of both flexibility and computer time reduction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
