Broadband pulse signals in an ocean waveguide as an inverse tool for the rapid extraction of some ocean properties

摘要

Abstract: With the inception of a new and fast normal-mode model that accurately simulates signals propagating in an ocean waveguide, it is possible to reconstruct pulse signals in the ocean. By measuring the pulse signals at different depths, one can extract a variety of information about the waveguide, such as ducting properties associated with the velocity profile, and some bottom properties that relate to the pulse widths. We present examples of the extraction data from this methodology. !7
