Abstract
A nulling direct radiating array (,) that includes a main phased array (,) and a plurality of auxiliary arrays (,) symmetrically disposed about the main array (,). The main array (,) includes a plurality of antenna elements (,) and a beam forming system (,) that generates one or more channels made up of several pixel beams. The pixel beams from the main array (,) are connected to a nulling processor (,) along with the combined signal from the antenna elements (,) of the auxiliary arrays (,). An adaptive weighting network (,) and an adaptive weight generator (,) within the nulling processor (,) determine whether a jamming signal exists in the channel beam, and weight the pixel beams from the main array (,) accordingly to block the jamming signal. The auxiliary arrays (,) provide a wider beam aperture that is able to more narrowly define the null in the radiation pattern of the main array (,).
