PALSAR2 polarimetric distortion matrix is measured using corner reflectors deployed in the Amazonian forest. The forest near geomagnetic equator provides ideal sites for assessment of L-band antenna parameters, at free Faraday rotation. Corner (CRs) rotation provide accurate estimation cross-talks contrast to biased measurements obtained with CRs significant extended Freeman–Van Zyl calibration...

SAR image acquired in the nighttime (10:30 PM local time) at the magnetic equatorial regions, i.e., Amazon, Africa, and the south East Asian areas, are often interfered by the streaks since the ALOS launch of the Jan. 24, 2006. These streaks appear both in amplitude image and phase of the SAR data, which contain the interferometric fringe and polarimetric phase. JAXA/EORC is conducting the quic...

Since 2014, Sentinel-1 (S1) Synthetic Aperture Radar (SAR) data have become an important source in the field of displacement detection thanks to regular acquisitions and 7.5 years temporal coverage at global level. Despite increasing number publications on role S1 landslide detection, there is still a need for research further clarify capabilities sensor applicable image analysis techniques. Pr...

The sensitivity of simulated flood depth and area to DEM resolution are acknowledged, but their effects on damage risk estimates less well understood. This study sought analyse the relative benefits using global DEMs different sizes, 5 m AW3D Standard, 12.5 ALOS PALSAR 30 SRTM, simulate inundation, risk. HEC-RAS 2D model was adopted for simulations, Toba River in Klang Basin Malaysia chosen cas...

1082-4006/08/14(01)-12$5.00 ©2008 The International Association of Chinese Professionals in Geographic Information Science (CPGIS) Abstract Satellite differential SAR interferometry has been widely accepted as a powerful tool to map co-, postand inter-seismic deformation since its successful application to the 1992 Landers Earthquake. As soon as the Ms8.0 Wenchuan Earthquake occurred on 12 May ...

A polarimetric ground-based radar (GB-radar) system operated in the L-band has been developed. The frequency range of GB-radar is 1.215 to 1.3 GHz, which is the same as that of Japanese satellite-borne SAR, PALSAR-2 (Phased Array type L-band Synthetic Aperture Radar), and Japanese L-band air-borne radar, i.e., Pi-SAR-L2 (Polarimetric and Interferometric Airborne Synthetic Aperture Radar L2). Po...

Space-borne synthetic aperture radar (SAR) data have been widely used to produce ice concentration (type), ice motion, ice charting (operational route planning), and iceberg detection. Recent availability of polarimetric SAR sensors (e.g., TerraSAR-X, RADARSAT-2, and ALOS PALSAR) enables us to explore the full potential of polarimetric data to derive sea ice information. Among the many sea ice ...
