Design technology of advanced synthetic aperture radar for space use

摘要

Synthetic Aperture Radar (SAR) is active microwave sensor for cloud-free and day-and-night observation. Several SARs for space use were launched and operated so far including Japanese JERS-1 SAR. This paper reports design technology of SAR, especially Phased Array type L-band Synthetic Aperture Radar (PALSAR) carried on Advanced Land Observing Satellite (ALOS).
