Abstract

In this paper, we consider the problem of optimum multi-domain real-time\nbeamforming and high-precision beam pattern positioning in application to very\nlarge wideband array antennas, particularly to the Square Kilometre Array (SKA)\naperture array antenna. We present a new structure for wideband space-frequency\nbeamforming and beamsteering that maximizes detectability of cosmic signals\nover the array operational frequency range.\n
