Abstract
Previous contracts resulted in the development and use of the program BREVER, which performs reverberation inversion using the sonar analysis suite DMOS. A more recent contract allowed for the expansion of DMOS to incorporate the use of the ray trace program Bellhop as an alternative to the normal mode theory program PMODES. The current contract called for the expansion of BREVER so that it is able to use the Bellhop-enabled version of DMOS. A User’s Guide for the newly expanded version of BREVER was also to be written as a separate document. Both of these tasks were accomplished. Initial testing of the BASE 04 configuration, performed as a prelude to analysis of that data, revealed a limitation of Bellhop previously unknown to both the author and the Scientific Authority. This limitation prevented using the expanded version of BREVER to perform reverberation inversion on the BASE 04 data, which was the last task on the current contract.
