SAR interferometry using ALOS-2 PALSAR-2 data for the Mw 7.8 Gorkha, Nepal earthquake
The Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”) has been observing Nepal with the Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) in response to an emergency request from Sentinel Asia related to the Mw 7.8 Gorkha earthquake on April 25, 2015. PALSAR-2 successfully detected not only avalanches and local crustal displacements but also continental-scale deformation. Es...
متن کاملRandom Forest Classification of Sediments on Exposed Intertidal Flats Using Alos-2 Quad-polarimetric Sar Data
Coastal zones are one of the world’s most densely populated areas and it is necessary to propose an accurate, cost effective, frequent, and synoptic method of monitoring these complex ecosystems. However, misclassification of sediments on exposed intertidal flats restricts the development of coastal zones surveillance. With the advent of SAR (Synthetic Aperture Radar) satellites, polarimetric S...
متن کاملAssessment of Polarimetric and Spatial Features for Built-up Mapping using ALOS PALSAR Polarimetric SAR Data
Fully polarimetric synthetic aperture radar (PolSAR) has the advantage for working at all time and all weather compared with optical remote sensing. It can provide four channel data, including HH, HV, VH, and VV, which is usually called sinclair matrix. The sinclair matrix can be used to describe the relative pure targets. Concerning to the distributed targets, it is necessary to use coherence ...
متن کاملDamage detection in the 2015 Nepal earthquake using ALOS-2 satellite SAR imagery
The Mw 7.8 earthquake jolted the central region of Nepal on April 25, 2015, and caused gigantic destruction. Satellite remote sensing is an effective tool to grasp damages in a wide area. In this study, preand post-event ALOS-2 satellite SAR data were used to detect affected areas in Kathmandu, the capital city of Nepal. Firstly, the crustal movements around the Kathmandu Valley were estimated ...
متن کاملPolarimetric Calibration of ALOS/PALSAR
This report presents the polarimetric calibration results of ALOS/PALSAR and discusses a stability of polarimetric calibration parameters during the calibration phase of ALOS and an influence of Faraday rotation on them. PALSAR is the first spaceborne polarimetric L-band synthetic aperture radar and its polarimetric data is expected to be utilized in various remote sensing applications. However...
