Abstract:

An array antenna comprised of n individual elements where n is an integer power of the base two. the individual elements have predetermined space code positions N which are varied by means of a plurality of tracking loops comprised of a portion of receiver apparatus coupled to the array and a null seeking detector which is adapted to vary the space code positions of the elements such that the elements are selectively spaced at respective N locations relative to the N locations to provide a predetermined 180 deg, phase difference between sets of elements operating in pairs at each space angle of arrival of each of M interference signals whereby a null and substantially complete cancellation of the interfering sources are simultaneously provided while retaining the ability to receive the desired signal at its peak received value.
