ABSTRACT:
A beam steering or scanning system comprising a plurality of groups of radiating elements each group of which is connected to a controllable array signal distribution means which is itself a plurality of phase shifters and/or timing delays or sequences appropriately weighted hereinafter referred to as the array beam former the spacial directional beams being generated and scanned by controlling the array beam former while contemporaneously controlling a sub-array beam forming system forming part of the beam steering system so as to modify the sub-array factors as well as the array factor whereby a resultant beam configuration is produced in which grating lobes are obviated or at least significantly suppressed.
