11. Sar Remote Sensing of Sea Ice: Towards automatic extraction of geophysical information
Sammanfattning : Synthetic Aperture Radar (SAR) images from the ERS-1 satellite have great potential for sea ice remote sensing due to its independence of daylight and clouds. The very high data rate of SAR (over 100 million bits per second) results in an enormous volume of data that threatens the ability of human interpreters. LÄS MER
12. Contribution to Wideband SAR Space-Time Processing, and Radar Remote Sensing of Sea Ice
Sammanfattning : Synthetic Aperture Radar (SAR) has the capability to map the Earth with high resolution and is used in both civilian and military applications. The development of SAR systems is going towards higher resolution. Today there are Wide Band (WB) SAR instruments that have a resolution actually smaller than the operating wavelength. LÄS MER
13. SAR Image Focus Errors due to Incorrect Geometrical Positioning in Fast Factorized Back-Projection
Sammanfattning : Synthetic Aperture Radar, SAR, is an aperture synthesis technique to generate an image of the ground from air or space with high resolution. Signal processing is performed in frequency domain with Fourier Transform techniques, or in time domain with Back Projection techniques. LÄS MER
14. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band
Sammanfattning : 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.
