A measurement of low-frequency reverberation was conducted in order to investigate features of sea surface and bottom scatterings in shallow water, where it is generally difficult to acquire sea surface and bottom reverberations separately. In the me

Low frequency sound propagation features and bottom sediment properties in shallow water were studied in the Shallow Water Acoustic Technology (SWAT) experiments conducted in the East China Sea. In these experiments, a hydraulic-type acoustic source

Bottom sediment properties at sites on the New Jersey Shelf and in the East China Sea were studied in the Shallow Water Acoustic Technology (SWAT) experiments. In these experiments, a source towed at constant depth transmitted low‐frequency cw sign

Geoacoustic parameters of bottom sediment have a great influence on acoustic propagation in a water column. In order to estimate the parameters, the genetic algorithm (GA) was applied to the low frequency acoustic data obtained at the SWAT (Shallow W

A stochastic inversion method is applied to the problem of determining sound‐speed profile in bottom sediment from modal eigenvalues, which can be observed from the FFT beamformed output of a horizontal array in a range‐independent shallow‐wate
