Abstract:

A formula is derived for the acoustic intensity reflected by an object of arbitrary shape embedded in a medium of variable index of refraction. Formulas are applicable in the ray acoustics limit. As specific applications, contours of equal intensity are calculated over a plane parallel to the ocean surface and over a plane perpendicular to the ocean surface when a plane wave of sound is reflected from ellipsoidal objects at various depths and distances from the receiver planes.
