Abstract

The Phased Array type L-band Synthetic Aperture Radar (PALSAR) on board the Advanced Land Observing Satellite (ALOS) scheduled for launch in June 2003 will be the Japanese second-generation spaceborne SAR following the Japanese Earth Resources Satellite-1 (JERS-1) SAR. The PALSAR is designed to achieve high performance and flexibility and the L-band data continuity of JERS-1. Active phased array antenna equipment provides variable incidence angle ranging from 8 to 50 degrees and allows ScanSAR operation. Especially, a full polarimetric function is the most challenging development. The JERS-1 SAR has demonstrated the advantage of L-band signals on SAR interferometry in vegetated areas. Based on the results from the JERS-1 SAR, applications of the PALSAR such as an environment monitoring, Earth science research will be enhanced. System characteristics and operational modes of the PALSAR and its expected applications are presented.
