An Unmanned Underwater Vehicle Defence System

Abstract

Nowadays, military threats are very close to us and cover terrestrial, aerial, and maritime attacks. This research defines a submarine defence system capable of monitoring and controlling a certain perimeter, based on submersible drones known as Unmanned Underwater Vehicles (UUV) and a grid of stations fixed to the seabed, which provides positioning acoustic signals as well as full-duplex digital communication using underwater acoustic modems. The novelty is the proposed 3D grid system with each Positioning Grid Element (PGE) being an Ultra-Short Baseline (USBL) low or medium operating range device and the processing
