A low-complexity MVDR beamformer for use with short observation times
D.N. Swingler · IEEE Transactions on Signal Processing · 1999
It is demonstrated, via simulation examples, that the steered, minimum-variance, subarray beamformer is a simple, viable, and computationally efficient approach to partially adaptive beamforming, with the additional advantage that it is available for use with short observation intervals where time is traded for bandwidth. A quadratically constrained version is also examined.
