The Phased Array L-band Synthetic Aperture Radar (PALSAR) aboard ALOS-1 was a successor sensor to the synthetic aperture radar on board JERS-1 with more advanced functions such as higher spatial resolution capability, variable off-nadir angles and additional modes such as full-polarimetry mode and ScanSAR mode.
Through the Online Dissemination server, ESA offers registered users access to the following data collections:
- ALOS PALSAR products: FBS, BFD, PLR and WB1 modes in RAW, GDH, GEC and SLC processing level
- ALOS PALSAR International Polar Year Antarctica: PALSAR data focused on polar regions
To find out more, visit PALSAR products information.
The goal of calibration and validation activities is to verify the accuracy and quality of data the instrument acquired.
Quality Control Reports
A small percentage of ALOS-1 PALSAR products processed by the current installed ESA IPF are affected by a known quality issue; IPF failures due to PRF changes.
