P waves transient scattering by 2-D penetrable targets: A direct solution

Abstract : The scattering of a transient acoustic Pwave by a two‐dimensional inhomogeneous fluid target is studied. An exact time‐domain formulation of the pressure is introduced and discretized. Discrete pressures are then computed by marching on in time and space. The convergence of this step by step procedure is examined numerically. Comparisons are made in the frequency domain with results obtained by another method. Influence of the size and of the sound velocity of a circular target is investigated.
