Bistatic Reverberation in Shallow Water: Modelling and DataComparison

Abstract

Bistatic and monostatic reverberation data were recorded in the2001 Asian Sea International Acoustic Experiment (ASIAEX). A modelbased on the normal mode theory has been developed to calculate bistaticbottom reverberation in shallow water and to explain the recorded data.The comparisons between the monostatic and bistatic reverberation dataare discussed, and the comparisons between model predictions andmeasured bistatic reverberation data are also presented. The numericaland experimental results show that the numerical predictions from thebistatic reverberation model fit the experimental data well, and thelong-range bistatic reverberation with a time delay can beapproximately expressed by the monostatic reverberation data.
