The simultaneous lobing technique, also known as monopulse technique, has been widely used for fast target localization and tracking purposes. Many works focused on accurately localizing one or two targets laying within a narrow beam centered around the monopulse antenna boresight direction. In this work, however, a new approach uses the outputs of a four quadrant antenna receiver to rapidly localize two point targets present in the hemisphere. A second set of antennas can be required to localize two targets sharing the same elevation or azimuth angles. To combine the outputs of both antenna sets and enhance the estimation performance of the algorithm, two methods are presented and compared.
