  1. 1. Factorized Geometrical Autofocus for Synthetic Aperture Radar Processing

    Author : Jan Torgrimsson; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Back-Projection; PGA; SAR; UWB; Autofocus; FGA;

    Abstract : Synthetic Aperture Radar (SAR) imagery is a very useful resource for the civilian remote sensingcommunity and for the military. This however presumes that images are focused. There are severalpossible sources for defocusing effects. For airborne SAR, motion measurement errors is the maincause. READ MORE

  3. 3. Sea Surface Current Measurements Using Along-Track Interferometric SAR

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Anis Elyouncha; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ocean remote sensing; Along-track InSAR; Synthetic aperture radar; Sea surface currents; SAR;

    Abstract : Ocean currents affect the weather, the climate and the marine ecosystem. Observing ocean currents is important for understanding the upper-ocean layer dynamics and its interaction with the other components of the climate system. In-situ measurements are sparse and their deployment and maintenance is costly. READ MORE

  4. 4. Modelling Microwave Backscattering from Sea Ice for Synthetic-Aperture Radar Applications

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Anders Carlström; [1995]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic-aperture radar; microwave; surface roughness; sea ice; backscattering models;

    Abstract : The spaceborne synthetic-aperture radar (SAR) is considered one of the key instruments for monitoring the ice cover in polar oceans and regional seas. This thesis is concerned with applications of electromagnetic scattering theory and SAR system theory for modelling the response of different types of sea ice in SAR imagery. READ MORE

  5. 5. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Maciej Soja; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic Aperture Radar; biomass estimation; modelling; forest;

    Abstract : Currently, one of the most uncertain factors in the global carbon cycle models lies in the terrestrialcarbon stock, mainly forests. The available methods for global forest resource mapping provide onlyrough estimates of biomass, the most relevant practical quantity related to carbon stock. READ MORE
