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

    Author : Jan Torgrimsson; Chalmers tekniska högskola; []
    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

  4. 2. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band

    Author : Erik Blomberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Tomography; SAR; L-band; EM Modelling; P-Band;

    Abstract : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.

  5. 3. Tectonic Evolution of the Zagros Suture-and Imbricate Zones in Iraq

    Author : Maher T. Zainy; Maria Ask; Francisco Gomez; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tectonic evolution; Zagros Fold-and Thrust Belt; Remote sensing; Field feological work; 3D geological modelling; Natural resources exploration; Applied Geology; Tillämpad geologi;

    Abstract : Orogenic belts are expressions of tectonic activity, often host various natural resources (e.g. petroleum and minerals reserves), and influence the society and environment through hazards (e.g. READ MORE

  6. 4. Glacier-Ocean Interactions in the Arctic : Contemporary calving and frontal melt from field observations, remote sensing, and numerical modelling

    Author : Felicity Alice Holmes; Nina Kirchner; Benedict T. I. Reinardy; Riko Noormets; Jason Briner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Glacier-ocean interactions; Arctic; Calving; naturgeografi; Physical Geography;

    Abstract : Globally, glaciers are losing mass as a result of the changing climate, with this mass loss having a considerable societal impact through rising sea levels. Glaciers which terminate in the oceans are particularly vulnerable to changing external conditions as a result of high sensitivity at their marine margins. READ MORE

  7. 5. The spectral reflectance of coniferous tree stands and of barley influenced by stress : an analysis of field measured spectral data

    Author : Johan Kleman; Stockholms universitet; []
    Keywords : spectral reflectance; field measurement; middle infrared; crops; fertilisation; irrigation; coniferous forest; helicopter; measuring geometry;

    Abstract : This thesis focuses on the spectral signatures for vegetation. Knowledge about the spectral characteristics of different vegetation types is imperative for an efficient use of existing remote sensing systems, and also to provide guidelines for sensor development. READ MORE
