  1. 1. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

  3. 2. Scanning range extension by combining arrays with lenses

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hairu Wang; [2022]
    Keywords : Dome Antenna; Dielectric Lens; Array Antenna; Kupolantenn; Dielektrisk lins; Array antenn;

    Abstract : Array antennas, and more specifically phased array antennas, are widely used in radar detection and communication systems because of their excellent beam scanning ability and simple control. Generally speaking, the scanning function can be realized in two ways: mechanically or electronically. READ MORE

  4. 3. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Cavell; [2022]
    Keywords : ;

    Abstract : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

  5. 4. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Colin Carlile; [2021]
    Keywords : Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

    Abstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE

  6. 5. Effects of Lattice Strain in Silicon Double Crystal Monochromators

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Johan Eckdahl; [2018]
    Keywords : synchrotron radiation physics max iv maxiv monochromator monochromation; Physics and Astronomy;

    Abstract : Silicon double crystal monochromators are standard in modern synchrotron hard X-ray beamlines. Their role is reducing a polychromatic photon beam to a small range of wavelengths, typically within a bandwidth of 0.01-0.1%. READ MORE
