An Entropic Framework for AUV Sensor Modelling
Author: Hanumant Singh
Publisher:
ISBN:
Category : Coherence (Optics)
Languages : en
Pages : 500
Book Description
This thesis examines the general task of active sensing by defining a measure of efficiency for sensing in a particular environment. We focus on fine-scale acoustic mapping from an autonomous underwater vehicle (AUV). The constraints on imaging underwater - vehicle power, vehicle hydrodynamics, computational and telemetry requirements, and typical navigational and attitudinal uncertainties along with the underlying physics of the acoustic sensing modality- are considered in defining an entropic measure of sensor efficiency. 675-kHz pencil-beam sonar data acquired using the JASON remotely operated vehicle in a challenging shallow water environment and 200-kHz echo-sounder data acquired using the ABE A UV are used to demonstrate the utility of the en tropic framework. We show the utility of an entropic framework for the following: (i) Optimizing the speed of the AUV for maximizing the information gathered with a particular sensor. (ii) the rate of convergence and the stability of our mapping efforts in the face of typical uncertainties in navigation and attitude; (iii) as a methodology for actual sensor deployment and use on a real vehicle; and (iv) in tasks such as post-mission analysis for applications such as change detection and path planning for subsequent missions.

Physical Oceanography of Continental Shelves
Author: K.H. Brink
Publisher: Princeton University Press
ISBN: 0691236461
Category : Science
Languages : en
Pages : 273
Book Description
An authoritative graduate textbook and professional reference on the physical dynamics of the coastal ocean This book provides an up-to-date, systematic treatment of the processes governing the velocity, pressure, temperature, and salinity of the coastal ocean. Written by a leading expert with decades of experience with theory, observations, and numerical models, it builds on the idea that knowledge of fundamental phenomena allows for an understanding of continental shelf waters globally. Featuring a wealth of ocean observations from a wide variety of locales, Physical Oceanography of Continental Shelves is an essential resource for both students and researchers on this critical region of the world’s oceans. Covers the physical dynamics and properties of the coastal ocean, synthesizing theory and global observations Topics include turbulent boundary layers, wind driving, coastal-trapped waves, the inner shelf, tides, buoyancy currents, instabilities, and connections with the deep open ocean Ideal for graduate students in physical oceanography Includes exercises to strengthen understanding and draws on the author’s experience teaching the subject A must for oceanographers and engineers seeking a comprehensive synthesis of continental shelf processes

Hydrographic Data from the U.S. Naval Oceanographic Office
Author: Carol A. Alessi
Publisher:
ISBN:
Category : Arabian Sea
Languages : en
Pages : 498
Book Description
Temperature-salinity-depth profile data were obtained for the Persian Gulf, Southern Red Sea and parts of the Arabian Sea from the Master Oceanographic Observations Data Set (MOODS), located at the U.S. Naval Oceanographic Office (NAVOCEANO), Stennis Space Center, Mississippi. These data were used as part of a physical oceanographic study of the Red Sea and Persian Gulf outflows. This report documents the organization of the data set, method of quality control used to eliminate unrealistic data, and provides a summary in graphic form of the hydrographic observations.
