Abstract
An efficient monopulse direction finding technique is based on the best algorithm in the least squares sense for a given antenna configuration. The algorithm simultaneously uses complex voltage data from all of the antenna ports, i.e., all of the available data received. No a priori emitter polarization information is assumed. Only a two dimensional search for the performance index minimum is needed to find the solution. The method is extended to N emitters with a search in only 2N space for the N emitter angles.
