摘要：
The relation between the sound reflection losses measured at fixed grazing angles and the characteristics of the sediment layer and the underlying half-space is considered. Based on this relation, a method of the reconstruction of the sea bottom characteristics is developed for a ocean bottom consisting of a single sediment layer overlaying a semi-infinite elastic half-space, Using this bottom model, the reconstruction of the characteristics of a layered elastic bottom is performed from the numerically simulated data with induced synthetic error. The work was supported by the RFBR (97-05-64712).
