Abstract:

The long-term goals of this work are to develop a theoretical model for predicting the reverberation in shallow water, to derive both small-angle seabed reflectivity and scattering strength from reverberation data at low frequency, and to understand the physical mechanism of sea bottom scattering. The scientific objective of this research is to investigate the effects of the sea bottom on sound propagation, reverberation and signal coherence in shallow water for a frequency range of 100 Hz-3000 Hz. Our specific objectives are I to simultaneously measure acoustic data and geologic and geophysical data at carefully chosen sea areas. II to derive sound velocity and attenuation in sediments from sound propagation. And III to characterize the seabottom scattering function from reverberation measurements.
