Abstract
An optimal strategy is presented for computing the far-field scattered by a reflector antenna with minimized computer time. The key point is the use of a sampling procedure which reconstructs the radiation diagram from the knowledge of a limited number of points. These points, in turn, are computed using numerical techniques or asymptotic methods, whichever is the most appropriate. The strategy is implemented for a two-dimensional configuration, namely a parabolic cylinder with off-focus illumination. Conclusions valid for the general tridimensional case are then drawn.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
