Query: Robust Capon Beamforming via Shaping Beam Pattern   High sidelobe level and direction of arrival (DOA) estimation sensitivity are
two major disadvantages of the Capon beamforming. To deal with these problems,
this paper gives an overview of a series of robust Capon beamforming methods
via shaping beam pattern, including sparse Capon beamforming, weighted sparse
Capon beamforming, mixed norm based Capon beamforming, total variation
minimization based Capon beamforming, mainlobe-to-sidelobe power ratio
maximization based Capon beamforming. With these additional structure-inducing
constraints, the sidelobe is suppressed, and the robustness against DOA
mismatch is improved too. Simulations show that the obtained beamformers
outperform the standard Capon beamformer.
