Scattering of an acoustic pulse by a rigid sphere on a sedimentary (fluid) bottom
- 27 Downloads
We study the problem of scattering of acoustic pulses on a rigid sphere located near the interface of two media in one of which (the bottom) sound absorption is taken into account. To find the amplitudes of the echo-signal in the distal field we apply the Fourier transform with respect to time and the method of T-matrices.
