Active phased-array L-band Synthetic Aperture Radar, sole imaging payload of the ALOS-4 satellite (launched 1 July 2024). Operated by JAXA, built on the JAXA Advanced Satellite Bus-3 by Mitsubishi Electric Corporation. Operates at L-band (selectable centre frequencies 1236.5 / 1257.5 / 1278.5 MHz), enabling deep canopy penetration for tropical forest disturbance detection. Principal advance over PALSAR-2 is the wider ScanSAR swath at finer resolution: 700 km swath at 25 m resolution versus PALSAR-2 350 km swath at 100 m. Stripmap modes 3 to 10 m resolution; Spotlight 3 by 1 m over 35 km scene. Dual polarisation (HH+HV) confirmed.
