Statistical performance of the MVDR beamformer in the presence of diagonal loading

Proceedings of the 2000 IEEE Sensor Array and Multichannel Signal Processing Workshop. SAM 2000 (Cat. No.00EX410), 2002
New results are derived that describe the statistical performance of the MVDR (minimum variance distortionless response) adaptive beamformer when the weights are computed utilizing the sample covariance matrix and diagonal loading. It is well known that undesirably high sidelobes are generated when the unaugmented sample covariance matrix is used as an

Equivalence of adaptive array diagonal loading and omnidirectional jamming

IEEE Transactions on Antennas and Propagation, 1995
Diagonal loading, where a diagonal matrix is added to the estimate of the covariance matrix, is often used in adaptive arrays to minimize the array's responsiveness to random fluctuations in the estimate of the interference environment. Poor estimates of the covariance matrix often result in high random sidelobes in the sample matrix inversion (SMI ...

Robust Adaptive Diagonal Variable Loading RLS Beamforming

INTERNATIONAL JOURNAL ON Advances in Information Sciences and Service Sciences, 2012
This paper deals with diagonal variable loading recursive least squares (VLRLS) array beamforming based on a generalized sidelobe canceller. In conjunction with a subweight partition approach, the VLRLS-based beamformer demonstrates the advantages of fast convergence speed, insensitivity to dynamic estimate modeling error, less computational load, and ...
