This paper presents a single receiver geoacoustic inversion method adapted for low-
frequency impulsive sources. It is applied to light bulb data collected during the Shallow
Water 2006 experiment. The inversion is carried out by extracting dispersion curves from the
received signal, and comparing them to simulated replicas. To achieve dispersion curve
estimation in the time-frequency domain, modal separability is improved using a signal
processing method called warping. The inversion scheme allows for a reliable estimation of …
