Abstract
A simple technique for obtaining wide-angular nulling in the sum and difference patterns of the monopulse antenna is presented. This technique involves the addition of two elements, one at each end of the monopulse antenna array, which together produce a cosine pattern used for obtaining wide-angular nulls. By adjusting the amplitude of the excitation of the two-element auxiliary array, it is possible to modify the overall array pattern to place wide angular nulls in the directions of undesired interference signals.
