  2. 1. 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

  4. 2. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

    Author : Klas Folkesson; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; windthrow detection;

    Abstract : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

  6. 4. Ultra-wideband synthetic aperture radar in the VHF-band: Image formation algorithms and interferometric applications

    Author : Per-Olov Frölind; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backprojection; wideband; VHF; DEM; SAR; CARABAS; signal processing; low frequency; interferometry;

    Abstract : Synthetic aperture radar (SAR) is a technology to generate high-resolution radar images for ground surveillance and mapping. By exploiting the lower VHF band, the attenuation reduces dramatically in forest areas compared to microwaves and new applications become feasible. READ MORE
