Robust Beamforming with Sidelobe Suppression for Impulsive Signals
Abstract
Beamforming is a fundamental technique in array signal processing. Many existing approaches are based on second-order statistics. However, their performance degrades significantly due to outliers in the received signal. In this letter, we propose an outlier-resistant beamformer design criterion based on minimizing the expectation of the modulus of the array output with an ${\ell _1}$-regularization term being added for sidelobe suppression.
