ACOUSTICODES: PASSIVE UNDERWATER ACOUSTIC MARKERS FOR NAVIGATION AND INFORMATION ENCODING FOR HIGH FREQUENCY SONARS
Abstract
The objective of this research effort is to demonstrate a novel passive underwateracoustic marking technology, based on stacked ela""stic layers (~AcoustiCode~), capable ofproducing unique echo sequences (i.e. acoustic signatures) when interrogated with highfreque""ncySONAR systems which can be leveraged for 3D navigation, routing and informationsignaling for autonomous underwater vehicle (AUV"). Such passive acoustic markers could beoperated at significantly longer standoff distances compared to underwater camera-based sy"stemand even in turbid/murky waters where visibility is quasi-null. Beyond applications for AUVsnavigation and signaling, other po""tential applications of AcoustiCodes include mine and assetlocation and underwater safe passage marking, hydrographic and oceanog""raphic survey, marinehazard marking and scientific instrumentation location as well as marking cables, flexible risersor telecom a"nd offshore power cable location.
