Abstract

This Phase I proposal is for transparent projectors to be used to add an active mode to a passive hydrophone array. This transparency is necessary to minimize the projectors effect on the hydrophone array performance. We present here a plan for this development which includes FEA modeling as well as some initial testing of modified in-stock projector candidates. We discuss various hydrophone array baffle conditions and how this affects the choice of projector type. The operation of some initial advanced projector design candidates, as well as a unique transparency means, are presented.
