Active phased-array L-band Synthetic Aperture Radar, sole imaging payload of the ALOS-2 satellite. Operated by JAXA, built by Mitsubishi Electric. Operates at L-band (centre frequency 1257.5 MHz, wavelength about 23.84 cm), enabling deep canopy penetration for tropical forest disturbance detection. Six resolution modes (Spotlight, Stripmap Ultrafine/High-Sensitive/Fine, ScanSAR Normal/Wide). Backbone of the JJ-FAST tropical deforestation alert system and JAXA's Annual Forest/Non-Forest Mosaic.
