Abstract
A new algorithm for the reconstruction of the two basic acoustic parameters of the sea floor (density and sound speed) is presented in this communication. A multilayer model for the ocean bottom is assumed and the data consist of reflection coefficient measurements (magnitude and phase) in the sea water for obliquely incident acoustic waves. Since the reconstruction of the two unknown parameters mentioned above is sought, an empirical formula between them must be used in the reconstruction algorithm. The algorithm is based on the use of a recursive formula for the local reflection coefficient above each interface of the sea bottom model. Finally, accurate reconstruction results, based on synthetically obtained reflection data, are obtained.
