Robust adaptive beamforming via target tracking
Saeed Gazor, Sofiène Affes, Yves Grenier · IEEE Transactions on Signal Processing · 1996
The proposed robust beamformer adaptively self-corrects and tracks desired-source location errors or variations regardless of the eigenstructure of the input correlation matrix, of the array shape and nature of the noise. It only requires an order of computations of the sensors number and performs nearly as well as MUSIC in localization.
