EMISAR: An Absolutely Calibrated Polarimetric - and -band SAR
EMISAR is a high-resolution (2 2 m), fully polarimetric, dual-frequency (Land C-band) synthetic aperture radar (SAR) system designed for remote-sensing applications. The SAR is operated at high altitudes on a Gulfstream G-3 jet aircraft. The system is very well calibrated and has low sidelobes and low cross-polar contamination. Digital technology has been utilized to realize a flexible and high...
متن کاملEMISAR: C- and L-band polarimetric and interferometric SAR
EMISAR is a Cand L-band fully polarimetric (i.e. 4 complex channel per frequency) synthetic aperture radar designed for remote sensing with high demands for resolution (2 m), polarization discrimination, and absolute radiometric and polarimetric calibration. The present installation has one 3axes stabilized antenna (Cor L-band) and two flush mounted C-band antennas providing the system with cro...
متن کاملEMISAR: A Dual-frequency, Polarimetric Airborne SAR
EMISAR is a fully polarimetric, dual frequency (Land Cband) SAR system designed for remote sensing applications. The data are usually processed to 2x2 m resolution. The system has the capability of C-band cross-track single-pass interferometry and fully polarimetric repeat-pass interferometry. The SAR is operated at high altitudes on a Gulfstream G-3 jet aircraft. The system is very well calibr...
متن کاملImproving Sea Ice Characterization in Dry Ice Winter Conditions Using Polarimetric Parameters from C- and L-Band SAR Data
Sea ice monitoring and classification is one of the main applications of Synthetic Aperture Radar (SAR) remote sensing. C-band SAR imagery is regarded as an optimal choice for sea ice applications; however, other SAR frequencies has not been extensively assessed. In this study, we evaluate the potential of fully polarimetric L-band SAR imagery for monitoring and classifying sea ice during dry w...
متن کاملBiomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band
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 uncertainti...
