This paper describes techniques for improving radar target search and angle estimation performance over the coventional monopulse processing in the elimination of beam-shape loss. Specifically, we have developed a scheme that uses multiple sets of monopulse beams. We also show how monopulse processing scheme and the maximum-likelihood scheme can be combined to bal-ance the performance and processing requirement. These techniques make use of digital beamforming of multiple simultaneous re-ceived beams and processing using multiple algorithms. Simulation results are included to show the improvement in target search and angle estimation and the elimination of beam-shape loss.
