Abstract:

The problem of target detection and localization in two-layered media can be solved by time reversal and reverse time migration mixed method. This paper is extended from two-layer layered medium to three-layered media. Due to the interference of two interfacial reflection signals, three-layered media is more difficult to detect than two-layer media. The single prominent mountain like acoustic field distribution is obtained around the target. For interface reflected signal, it is a disordered and inhomogeneous acoustic field distribution with a smaller amplitude. The position of summit is the just position of the target, thus achieving the detection and positioning of the target. © 2019 IEEE.
