Diffraction of a plane acoustic wave on an elastic sphere located near the bottom

On the basis of numerical computations we analyze the echo-signals from a steel spherical shell located near the bottom of water under the action of a quasimonochromatic pulse. We study the effect of the distance between the sphere and the bottom on the echo-pulse. Translated fromMatematichni Metodi i Fiziko-mekhanichni Polya, Vol. 40, No. 1, pp. 79–84.
