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

    University essay from Uppsala universitet/Signaler och system

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

    Abstract : 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. READ MORE

  3. 2. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS
