  1. 21. Radar Measurements of Temporal Variation in a Boreal Forest

    Author : Albert Monteith; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; remote sensing; temporal variation; tomography; antenna array; temporal coherence; Synthetic aperture radar SAR ;

    Abstract : Synthetic aperture radar (SAR) on a satellite platform is a suitable technique for all-weather global monitoring of forest parameters such as biomass. This is important for increasing the accuracy of the global terrestrial carbon flux, the largest uncertainty in our current understanding of the Earth’s carbon cycle. READ MORE

  2. 22. SAR Remote Sensing of Forests, from Microwaves to VHF

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

    Abstract : 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. READ MORE

  3. 23. Sea Ice and Ocean Environmental Applications of Spaceborn SAR

    Author : Sverre Thune Dokken; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radarsat; SSM I; ERS-1 2; ocean applications; sea ice applications; numerical models; SAR; Arctic Ocean; Envisat; climate change;

    Abstract : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 25. Estimation of change in forest variables using synthetic aperture radar

    Author : Ivan Huuva; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Large scale mapping of changes in forest variables is needed for both environmental monitoring, planning of climate actions and sustainable forest management. Remote sensing can be used in conjunction with field data to produce wall-to-wall estimates that are practically impossible to produce using traditional field surveys. READ MORE
