The Sonar Simulator for Underwater Navigation
Position of surface objects can be fixed in many ways. The most popular radionavigational systems, including satellite systems, make possible obtaining nearly continuous and very precise ship’s position. However, under the water application of radionavigational systems is impossible. Underwater navigation requires other tools and solutions then these encountered in surface and air navigation. I...
متن کاملUsing Sonar in Terrain-Aided Underwater Navigation
Using Sonar in Terrain-Aided Underwater Navigation P.Newman H.Durrant-Whyte Department of Mechatronics University of Sydney, NSW. 2006, Australia e-mail pauln/hugh@mech,eng.usyd.edu.au In many ways autonomous navigation of underwater vehicles is a ‘holy grail’ of subsea robotics. For an AUV to continually estimate its pose (position and orientation) and operate within an initially unknown envir...
متن کاملUnderwater navigation based on passive electric sense: New perspectives for underwater docking
In underwater robotics, several homing and docking techniques are currently being investigated. They aim to facilitate the recovery of underwater vehicles, as well as their connection to underwater stations for battery charging and data exchange. Developing reliable underwater docking strategies is a critical issue especially in murky water or/and in confined and cluttered environments. Commonl...
متن کاملTerrain Based Navigation Tools for Underwater Vehicles Using Eigen Analysis
The development of tools for Terrain Based Navigation of Underwater Vehicles rooted on Principal Component Analysis are proposed and discussed in detail. Resorting to a nonlinear Lyapunov transformation, the synthesis and analysis of a nonlinear multirate H2 estimator is presented with guaranteed stability and optimal performance on equilibrium trajectories. Post-processing techniques using a f...
متن کاملFINAL REPORT Sensor Phenomenology and Feature Development for Improved Sonar-based Detection & Classification of Underwater UXO SERDP Project MM-1533
This effort has examined the problem of detection and classification of buried munitions in underwater environments. We have focused on the use of low frequency sonar since high frequency acoustic waves are strongly attenuated by sediments. The focus of this effort has been to process low-frequency data collected from the Buried Object Scanning Sonar (BOSS) into 3D imagery using beamforming, an...
