Abstract
It is demonstrated that adaptive beamforming techniques are superior to conventional methods for the spatial processing of sonar array data. For purposes of comparison, both conventional and adaptive frequency-wavenumber spectra are presented for various sonar arrays. Adaptive processing is found to improve the spatial resolution performance of an array of acoustic sensors and to suppress the spatial leakage inherent in conventional processing.
