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

    Författare :Anders Carlström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic-aperture radar; microwave; surface roughness; sea ice; backscattering models;

    Sammanfattning : 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. LÄS MER

  4. 3. Radar Remote Sensing of Forests Using CARABAS and ERS

    Författare :Gary Smith Jonforsen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clear-cut; stem volume; ERS; forest; interferometry; remote sensing; SAR; biomass; CARABAS;

    Sammanfattning : Forests cover more than 30% of the Earth's land surface, and represent an important resource. In order to manage this resource effectively, accurate and up-to-date information is required on the extent and state of the forests. Radar remote sensing offers the possibility of providing some of this information. LÄS MER

  5. 4. SAR Remote Sensing of Forests, from Microwaves to VHF

    Författare :Hans Israelsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave; backscattering models; SAR; VHF; vegetation;

    Sammanfattning : The number of SAR systems available for civilian remote sensing purposes has grown in the nineties. A Synthetic Aperture Radar produces high resolution images of the earth independent on daylight and atmospheric conditions. This thesis mainly examines the applications of SAR remote sensing to monitoring forested areas. LÄS MER

  7. 5. From Fauna to Flames : Remote Sensing with Scheimpflug Lidar

    Författare :Elin Malmqvist; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Lidar; Laser radar; Scheimpflug lidar; Combustion diagnostics; Entomological lidar; Lidar; Laser radar; Scheimpflug Lidar; Combustion diagnostics; Entomological Lidar; Fysicumarkivet A:2019:Malmqvist;

    Sammanfattning : This thesis presents applications of the Scheimpflug Lidar (S-Lidar) method. The technique has been applied to combustion diagnostics on a scale of several meters as well as fauna detection and monitoring over distances of kilometers. LÄS MER
