Underwater sound receiver with optimized covariance matrix

摘要

An underwater sound receiver (20) is shown with a multiplicity of sound transducers (22) which are each designed to convert incoming sound waves (24) into a signal (26). A signal processor (28) is designed to determine an empirical covariance matrix based on the signals (26) and to optimize the empirical covariance matrix in order to obtain an optimized covariance matrix. The signal processor (28) is designed to form the direction of the sound waves (24) based on the optimized covariance matrix.
