Abstract :
In this letter, it is shown how to extend York´s phase-shifterless beam steering technique to difference pattern scanning for monopulse applications. By making a simple modification to the coupling between the central elements of a one-dimensional array, the effective equivalence of the steered sum and difference problems is established.
