Steering vector errors and diagonal loading [PDF]
IEE Proceedings - Radar, Sonar and Navigation, 2004 Diagonal loading is one of the most widely used and effective methods to improve robustness of adaptive beamformers. The authors consider its application to the case of steering vector errors, i.e. when there exists a mismatch between the actual steering vector of interest and the presumed one. More precisely, the problem addressed is that of optimally

Steering vector uncertainties and diagonal loading [PDF]
Processing Workshop Proceedings, 2004 Sensor Array and Multichannel Signal, 2005 In this paper, we study the performance of diagonally loaded beam-formers in the presence of steering vector errors i.e. when there exists a mismatch between the actual steering vector of interest and the presumed one. We consider the problem of optimally selecting the loading level with a view to maximise the signal to interference plus noise ratio ...

MVDR Algorithm Based on Estimated Diagonal Loading for Beamforming [PDF]
Mathematical Problems in Engineering, 2017 Beamforming algorithm is widely used in many signal processing fields. At present, the typical beamforming algorithm is MVDR (Minimum Variance Distortionless Response). However, the performance of MVDR algorithm relies on the accurate covariance matrix. The MVDR algorithm declines dramatically with the inaccurate covariance matrix. To solve the problem,
