Diffraction about Acoustically Soft Panels
Abstract
The use of two-dimensional shaded and unshaded arrays to discriminate against diffraction about acoustically soft panels is investigated numerically by the use of a two-dimensional boundary element integral method. Calculated predications for infinitely long strips are used to estimate the diffracted field at a hydrophone array behind a square baffle. The diffraction floor of the hydrophone array is determined by weighting the array elements with various shading coefficients. Comparisons of diffraction discrimination by a hydrophone array versus a single hydrophone at various positions are presented. Keywords: Acoustically soft panels; Boundary integral method; Diffraction; Shaded hydrophone arrays.
