Abstract

The Phased Array type L-band Synthetic Aperture Radar (PALSAR) is one of the imaging sensors onboard the Advanced Land Observing Satellite (ALOS) launched on January 24, 2006. The antenna of PALSAR is beam steerable to realize a variety of off-nadir angles. There are multi-polarimetric (dual and quad) observation modes and single polarimetric modes. It has also ScanSAR modes to observe a wide swath (250 km-350 km). PALSAR Ground Data System (GDS) has been developed at ERSDAC since 1999. In the system, raw data provided from JAXA are processed to SAR images as final products which are archived and distributed to the worldwide users. The SAR data processor of PALSAR GDS is designed to achieve optimal data quality as well as maximum performance to meet the requirements from various users.
