An approach for side lobe reduction in conventional beamformers
P. R. Mini, S. Mridula, Pezholil Mohanan · 2012
Conventional beamformers are simple and robust but since their side lobe levels are high, they are susceptible to interference from undesired directions. In this paper a method of reducing the side lobe levels of a conventional beamformer using a combination of wavelet denoising and tapering is proposed.
