Abstract : A monopulse radar having a single set of adaptive weights shared by both sum and difference channels. The radar utilizes algorithm that effect simultaneous nulling in the sum and difference patterns of its phased array antenna. Algorithms are developed for both amplitude and phase nulling and for phase only nulling. (Author)
