Abstract :
Frequency-wavenumber spectral analysis is developed for analysis of signals captured by circular sonar arrays. Following a general discussion of the technique, it is then applied to sea trial data. The usefulness of the technique for investigating self-noise in circular sonar arrays is demonstrated.
