Abstract :
Adaptive nulling in an array-fed offset paraboloidal reflector is considered. A narrow band system is assumed. It is also assumed that the signals received from the array feed can be weighted in both amplitude and phase and then summed to form the array output. The particular adaptive nulling algorithm used here is the generalized sidelobe canceller. H-plane design, adapted, and quiescent patterns are presented.<>
