Curvilinear wideband, projected derivative-matched, continuous aperture acoustic transducer

摘要

A curvilinear wideband, projected derivative-matched continuous aperture acoustic transducer includes a first curvilinear sensor having a predetermined spatial shading which is constrained to zero at its ends and has amplitude continuity between its ends; and a second curvilinear sensor area having a spatial shading which is the projected spatial derivative of the spatial shading of said first area and which has a discontinuous amplitude at its ends; the first and second spatially shaded areas being superimposed and coextensive along the sensing axis.
