Journal ArticleDOI
PALSAR Radiometric and Geometric Calibration
TL;DR: This paper summarizes the results obtained from geometric and radiometric calibrations of the Phased-Array L-Band Synthetic Aperture Radar on the Advanced Land Observing Satellite, which has been in space for three years.
Journal ArticleDOI
An L-Band Ocean Geophysical Model Function Derived From PALSAR
Osamu Isoguchi,Masanobu Shimada +1 more
TL;DR: The derived relation indicates that the wind sensitivity of the L-band NRCS is less than that of the C-band at moderate winds and large incidence angles, whereas comparable at stronger winds ((>10 m/s) and small incidence angles).
Journal ArticleDOI
The PALSAR Polarimetric Mode for Sea Oil Slick Observation
TL;DR: Results demonstrate for the first time that L-band polarimetric SAR measurements are useful for oil slick observation purposes and witness the capability of the ALOS PALSAR data for such application.
Journal ArticleDOI
Assessment of ALOS PALSAR 50 m Orthorectified FBD Data for Regional Land Cover Classification by Support Vector Machines
TL;DR: This paper investigates the relevancy of PALSAR orthorectified FBD product at 50-m resolution for regional land cover classification by the support vector machines (SVM) and confirms the high potential of the P ALSAR sensor for forest monitoring at regional, if not global scale.
Journal ArticleDOI
Quasi-stationary jets transporting surface warm waters across the transition zone between the subtropical and the subarctic gyres in the North Pacific
TL;DR: In this paper, surface flow jets and associated sea surface temperature (SST) distribution are investigated in the northwestern North Pacific, using satellite-derived surface currents and SST data that can resolve fine spatial scale structure.
