Minimize PALSAR
Instrument image

PALSAR (Phased Array type L-band Synthetic Aperture Radar) is an L-band SAR with 10 and 100 m resolutions that are capable of detailed, all-weather, day and night observations and repeat-pass interferometry. PALSAR has a ScanSAR observation mode, with a swath (250-350 km) that is three to five times wider than conventional SAR images. ScanSAR mode will be useful for monitoring sea ice and rain forest extent.
