Abstract : The purpose of this paper is to show how linear filter theory, usually applied to time-frequency problems, can be used to describe the properties of circular and cylindrical arrays of hydrophones when followed by a linear multi-beam processor. Examples of this approach are presented for a circular array; both for the monochromatic and for the broad-band cases. A first attempt is also shown of the extension of this method to a cylindrical configuration. (Author)
