Abstract

The authors propose an efficient scheme for extracting the complex bottom reflection coefficient (phase and amplitude) in a shallow-water waveguide by using the WKB modal condition. The input data are the measured modal wave number and the modal attenuation. This scheme is efficient because there are no replica calculations as in the conventional matched-field processing (MFP). Numerical simulations illustrate that the proposed scheme works well in different scenarios of shallow-water waveguides
