Abstract : A monopulse radar having a single set of phase shifters shared by both sum and difference channels. The radar utilizes an algorithm that effects simultaneous nulling in the sum and difference patterns of its phased array antenna. An algorithm is developed for phase-only nulling which does not require knowledge of the location of interference sources. (Author)
