Abstract
A novel aperture synthesis method is proposed for a broad-band beam (BB) generation, which supports a nondispersive time-signal transmission to a single observation plane. This plane, regarded here as the image plane (IP), is perpendicular to the axis of propagation and its location can be varied continuously from the near-field zone to the far-field zone. The spatial field of the BB at the IP can be shaped by modifying the classical spatial filtering synthesis techniques to construct a predetermined localized space-time (ST) field. The method characteristics, effectiveness, and simplicity, are demonstrated through two opposing analytic examples: Gaussian and rectangular source-field-distributions (SFD's).
