Detection of a submerged object insonified by beach noise

1993 
In a previous paper, numerical simulations were performed which demonstrated that a submerged object insonified by surface noise in an ocean waveguide can be detected at low to mid frequency for realistic arrays within about 1‐km range [Makris et al., J. Acoust. Soc. Am. 92, 2416 (A) (1992)]. For the present paper, an investigation into the possibility of detecting a submerged object insonified by low‐ to mid‐frequency beach noise in an ocean waveguide was carried out. Model beach noise is defined as a one‐dimensional array of uncorrelated surface sources and the detectability of the object is investigated for various orientations of the sensing array axis, beach axis, and object.
