ABSTRACT:
The arrangement includes N inputs each having an input signal thereon from a different one of N groups of elements of a phased antenna array, where N is an even integer greater than one and where the array is pointed only at a desired signal source, a first circuit to produce from the input signals M sum signals each having the desired signal received by the array and at least one jammer signal and M difference signals each having only the jammer signal, where M is an integer, and a second circuit responsive to each of the M sum signals and at least a selected one of the M difference signals to produce a resultant output signal having the desired signal with the jammer signal eliminated or at least greatly reduced.
