Abstract

Reliable and efficient techniques for solving geoacoustic inverse problems have been developed. A coordinate rotation technique can be used to identify the best resolved combinations of parameters for a given frequency and configuration of hardware [M. D. Collins and L. Fishman, J. Acoust. Soc. Am. 98, 1637–1644 (1995)]. Problems involving a vertical array of receivers at short range can be solved in a few seconds with an implementation of the self starter that is based on the method of undetermined coefficients [D. K. Dacol and M. D. Collins, J. Acoust. Soc. Am. (accepted for publication)]. These techniques are applied to data that were obtained in the Straits of Florida during the KWIX ’98 experiment.
