Extraction of Modal Back-Scattering Matrix from Reverberation Data in Shallow-water Waveguide

摘要

Linear inversion scheme is proposed to extracting the modal back-scattering matrix from reverberation data in shallow-water waveguide without any a priori assumption on the behavior of back-scattering. Both mode resolvable case (mode-filtering operating by a vertical line array) and mode un-resolvable case are discussed.
