  1. 1. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Erica Svensson; [2022]
    Nyckelord :Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

    Sammanfattning : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. LÄS MER

  3. 2. Physics-Informed Deep Learning for System Identification of Autonomous Underwater Vehicles : A Lagrangian Neural Network Approach

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Badi Mirzai; [2021]
    Nyckelord :AUV; System Identification; Deep Learning; Physics-Informed Deep Learning; Lagrangian Neural Networks; AUV; System Identifiering; Djupinlärning; Fysik-Informerad Djupinlärning; Lagrangianska Neurala Nätverk;

    Sammanfattning : In this thesis, we explore Lagrangian Neural Networks (LNNs) for system identification of Autonomous Underwater Vehicles (AUVs) with 6 degrees of freedom. One of the main challenges of AUVs is that they have limited wireless communication and navigation under water. LÄS MER

  4. 3. Efficient Energy Use of FPGA for Underwater Sensor Network

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Erik Amgård; Kevin Bergman; [2019]
    Nyckelord :Underwater Sensor Network; FPGA; FFT; VHDL;

    Sammanfattning : Operational time is becoming an increasingly important aspect in electronic devices and is also highly relevant in Underwater Acoustic Sensor Networks (UWSN). This thesis contains a study which explores what can be done to de-crease power consumption while maintaining the same functionality of an FPGA inside an underwater sensor-node network. LÄS MER

  5. 4. Evaluation of the LSTS Toolchain for Networked Vehicle Systems on KTH Autonomous Maritime Vehicles

    Master-uppsats, KTH/Marina system

    Författare :Elias Strandell Erstorp; [2015]
    Nyckelord :;

    Sammanfattning : The department of Naval Architecture at the Royal Institute of Technology is in posession of one Autonomous Underwater Vehicle (AUV) and a second is under construction. A project for doing hydrographic mapping using an Autonomous Surface Vehicle (ASV) is also initiated. LÄS MER
