A numerical study of rough interface reverberation suppression, clutter elimination and target resonance excitation in heterogeneous media with single channel iterative time reversal.

Abstract: The presence of echo returns from the rough interface of two layered medium, and the clutter of volume scattering hinders the detection of target buried in heterogeneous media. The situations are often raised in ultrasonic breast tumor diagnosis and underwater acoustic buried mine detection. This work investigates the application of monostatic single channel iterative time reversal in mitigating the difficulties with a numerical study. Simulations based on pseudospectral finite-difference time-domain method ar… Show more
