Iterative robust adaptive beamforming
The minimum power distortionless response beamformer has a good interference rejection capability, but the desired signal will be suppressed if signal steering vector or data covariance matrix is not precise. The worst-case performance optimization-based

Robust adaptive beamforming based on covariance matrix reconstruction with annular uncertainty set constraints. [PDF]
A robust adaptive beamforming method based on the interference covariance matrix reconstruction with annular uncertainty set constraints is proposed to address the issues of covariance matrix mismatch and steering vector mismatch caused by the distortion

Neural Network-Based Robust Adaptive Beamforming [PDF]
When adaptive arrays are applied to practical problems, the performances of the existing adaptive algorithms are known to degrade substantially in the presence of even slight mismatches between the actual and presumed array responses to the desired signal.

Robust adaptive beamforming with mainlobe maintenance of monopulse beams [PDF]
Adaptive monopulse approaches for angularly localising a main-beam target in jamming are usually based on variations of the concept of optimising the sum (Σ) beam via standard adaptation and then optimising the delta (Δ) beam subject to maintain the ...

An Approximate Algorithm for Robust Adaptive Beamforming [PDF]
This paper presents an adaptive weight computation algorithm for a robust array antenna based on the sample matrix inversion technique. The adaptive array minimizes the mean output power under the constraint that the mean square deviation between the ...
