    POLARIMETRIC ANALYSIS OF AIRBORNE DLR-ESAR DATA FOR VEGETATION CHARACTERIZATION INTRODUCTION: Polarimetry is the measurement and interpretation of different polarizations of electro-magnetic waves. Synthetic Aperture Radar (SAR) has been proven to be a powerful earth observation tool and emerging. To this aim, in this paper we present a novel approach for monitoring grassland dynamics based on polarimetric high-resolution SAR imagery, which is capable of handling either dual- or quad-polarization multi-temporal data and supports targeted classification. Repeat pass polarimetric data is then used to monitor the temporal change in flooded vegetation. This information is useful for a variety of applications in wetland mapping and monitoring. This paper will present a novel Curvelet-based technique for the enhancement of polarimetric decomposition channels as well as temporal differences in these Cited by: 2. various applications related to earth resource studies and monitoring of the environment. Recently, resolution of remote sensing data has been improved in visible images as well as Synthetic Aperture Radar (SAR) images. Polarimetric Airborne Synthetic Aperture Radar (AIRSAR) data that was used are fully polarized C band, L band and P band data.

Abstract. Tropical forest degradation has been a major area of interest for the remote sensing community. Various sensors have been dedicated to monitor its changes; however, due to widespread cloud cover, limited information could be retrieved through optical by: The use of radar data in recent studies of tropical forests has demonstrated several applications: the characterization of tropical forest typology [9] and [10]; the analysis of polarimetric.

Therefore, SAR is preferred for the estimation of forests parameters. Previous studies have already shown the potential of polarimetric SAR in the estimation of forest parameters using single and dual polarised SAR data for estimation of AGB (Le Toan et al.,Lo Seen et al.,Mitchard et al.,Morel et al., ).Cited by: There is an increasing need for fast and accurate data on tropical land cover status, and a baseline for land cover monitoring.

Remotely sensed SAR data are not sensitive to cloud cover and can be useful for such purpose. Polarimetric SAR data are available in orbital systems, such as RADARSAT-2, and still have to be tested for the classification of tropical land cover and the detection of.
