摘要：

A scheme based on the acoustic ray tracing method is proposed to obtain target location and parameter inversion in layered media containing solids with unknown parameters. The longitudinal wave velocity of the upper medium is acquired by measuring the head wave or direct wave propagation. The wave modes of signals received by a linear array are identified using their travel time and amplitude. The position and shape of the interface and the shear wave velocity of the upper solid medium are obtained by processing interface-reflected waves. The acoustic velocity of the lower medium and the target position are determined by processing the target-scattered waves with the minimum dispersion method in single-transmitter and multiple-receiver configurations. The steel-copper, aluminum-water, and water-plexiglass layered media with different interface shapes are selected for experimental verification. The results show that the inversed media parameters and target localization results agree with the actual values.
