Abstract
All beamspace DOA estimation algorithms are based on the beam outputs and the beamformers play an important role in providing high quality beam output data for further processing. In this paper, we use null-broadened MVDR beamformers to apply to the element outputs. The broadened null can reject the interfering sources not only from a specific direction but from a specific spatial region as well. Performance of beamspace MUSIC using null broadened beamformers is studied via computer simulation for uniform linear array. The simulation results show that the proposed scheme has good spatial resolution than conventional beamspace DOA estimation algorithms.
