3 October 2011 Development status of PALSAR-2 onboard ALOS-2
Author Affiliations +
The Advanced Land Observing Satellite-2 (ALOS-2) carries the state-of-the-art L-band Synthetic Aperture Radar (SAR) called PALSAR-2. PALSAR-2 has a Spotlight mode (1 to 3 m), a Stripmap mode (3 to 10 m) and a ScanSAR mode, whilst PALSAR onboard ALOS had 10 m spatial resolution at best. The new technologies, such as maximum bandwidth allocation for L-band SAR, the spotlight mode with Active Phased Array Antenna, high power efficiency device of GaN and chirp modulation technique, have been verified by testing its Engineering Model (EM). The critical design of ALOS-2 including PALSAR-2 was completed in June 2011. This paper describes current development status of ALOS-2 and brief results of EM.
