ICEYE X-band SAR

X-band synthetic aperture radar imager operating at 9.65 GHz, the sole imaging payload of the ICEYE satellite constellation. ICEYE has fielded three sensor generations: Gen 2 (300 MHz chirp bandwidth, 1 m finest resolution), Gen 3 (600 MHz, 0.5 m), and Gen 3.5 (1200 MHz, 0.25 m). All generations use VV single-polarisation and an electronically steered phased-array antenna. Modes span Dwell Precise (0.25 m, 5 x 5 km) through Scan Wide (27 m, 200 x 300 km). Satellites are ITAR-free and operate in sun-synchronous orbits. As of early 2026 the constellation comprises 60+ satellites.
