To use adaptive beamforming in underwater acoustics, this paper considers processing data in short rank-deficient blocks so the moving interferers will not move as far per block. As a baseline algorithm, we consider the traditional minimum variance distortionless response (MVDR) formula using a data sample covariance matrix inversion (SMI) with diagonal loading added to limit the downward bias and signal cancellation associated with rank deficiency. As a new algorithm, we use the multistage… CONTINUE READING
