Abstract/OtherAbstract:

Underwater acoustic data communication is critical for naval and scientific underwater missions. For example, high-rate telemetry between underway autonomous underwater vehicles (AUVs) and surface platforms can facilitate adaptive sampling of the ocean. Multiple-inputmultiple-output (MIMO) systems can deliver significant increased channel capacity for underwater communications. At the University of Delaware, an acoustic MIMO communication testbed on a Gavia AUV has been developed for digital communication measurements at the frequency band of 20-30 kHz. The Gavia AUV is a modular, small-size vehicle (20 cm in diameter, 77 kg in air) with a depth rating of 200 m. With advanced navigation systems (INS) and surface communication capabilities (WiFi and Iridium), it has been tested through various coastal-ocean missions. The MIMO system on board is designed for easy, low-cost deployment, and is capable of conducting acoustical sampling via a towed array with or without single-element or multi-element source transmission. In the presentation, the design concept, component detail, and engineering test results will be shown. [Work supported by ONR 321OA.]. |
