First Assessment of Polarimetric Images from Alos - Palsar: Check of Polarimetric Calibration and Assessment of Land - Cover Classification Potential
نویسندگان
چکیده
This study is a first assessment of fully polarimetric SAR data from the Advanced Land Observation Satellite (ALOS) – Phased Array type L-band Synthetic Aperture Radar (PALSAR) over the test-site of Oberpfaffenhofen in Germany. The polarimetric calibration is checked by using corner reflectors on the Oberpfaffenhofen test-site. Further, the fully polarimetric images are classified by using the unsupervised H / A / α – Wishart Classification, based on entropy, anisotropy and alpha decompositions and supervised Wishart Classification. The potential in discerning land-cover classes is assessed by comparing them to optical images.

Polarimetric calibration and validation for ALOS/PALSAR
The objectives of my proposal are to calibrate and validate the polarimetric data acquired by ALOS (Advanced land observing satellite)/PALSAR (Phased array type L-band synthetic aperture radar). In this report, we show the polarimetric calibration parameter of PALSAR derived by Quegan method and Amazon data. Moreover, we confirm the accuracy of Faraday rotation angle derived from PALSAR data as...
متن کاملInitial Polarimetric Calibration of PALSAR
This paper discusses an initial polarimetric calibration of ALOS PALSAR. ALOS was launched on January 24, 2006. PALSAR, which is one of ALOS three sensors, is the first spaceborne L−band polarimetric synthetic aperture radar. It is expected that PALSAR polarimetric data is used for many applications such as agriculture, forestry, ocean, natural disasters etc. Thus, polarimetric calibration is a...
متن کاملALOS−PalSAR Pol−InSAR Data Analysis: First Results
This paper presents a first calibration and quality analysis of Pol−InSAR data acquired by the ALOS−PalSAR based on deterministic and extended scatterers. The calibration of Pol−InSAR data requires the estimation and compensation of polarimeteric and interferometric system and propagation (through the ionosphere and atmosphere) induced distortions. Constant phase errors/offsets appear in the po...
متن کاملMapping Coastal Wetlands Using Polarimetric Alos Palsar Data in North Carolina
The purpose of this study is to map wetlands using multi-polarimetric and polarimetric analysis of ALOS Palsar data in coastal North Carolina. Radar sensor offers reliable acquisition of wetlands which are mandated, by Congress, to be mapped every ten years. Radar data products were generated using Wishart supervised (HH-HVVV) and Wishart unsupervised (entropy and dominant scattering mechanism)...
متن کاملThe Influence of Polarimetric Parameters and an Object-Based Approach on Land Cover Classification in Coastal Wetlands
The purpose of this study was to examine how different polarimetric parameters and an object-based approach influence the classification results of various land use/land cover types using fully polarimetric ALOS PALSAR data over coastal wetlands in Yancheng, China. To verify the efficiency of the proposed method, five other classifications (the Wishart supervised classification, the proposed me...
