Abstract
This paper describes geoacoustic characterization of a range-dependent environment using towed horizontal array data. Data from multiple points along a track are inverted using a short-range, range-independent scheme and the results are combined to produce a range-dependent model. Data from the MAPEX 2000 experiment, conducted by SACLANT Centre in the Mediterranean Sea, are used to determine seabed properties for a range-dependent environment. Inversion results are compared for both normal-mode and ray theory forward models. The layering structure of the range-dependent model compares favorably with a high-resolution seismic profile.
