Systolic MVDR beamforming with inverse updating
Marc Moonen · IEE Proceedings F Radar and Signal Processing · 1993
A stable alternative is described for the ‘standard’ systolic MVDR beamforming algorithm of McWhirter and Shepherd, which suffers from numerical instability. The alterative algorithm is similar to covariance-type recursive least squares algorithms, and is therefore readily implemented on an RLS systolic array.
