HY-2C Radar Altimeter

Dual-frequency Ku/C-band radar altimeter flown on HY-2C.

HY-2C Radar Altimeter is a dual-frequency active radar altimeter in the HY-2C microwave payload suite, flown on HY-2C, also known as Hai Yang 2C.^[1]^[2]^[3] It operates at Ku-band 13.58 GHz and C-band 5.25 GHz.^[1]^[3] The component supports sea-surface-height and ocean-dynamics observation within the HY-2 series mission objective.^[2] Its pulse-limited footprint is 2 km, with nadir ranging measurement accuracy of 2 cm.^[3] Host-satellite context includes a 957.583 km average height and a 1336 km drifting-orbit altitude; these are mission-level values, not altimeter component measurements.^[2]^[1] Radar altimetry is demonstrated on HY-2C, with ALT active from December 2020 and expected end of life at or after 2026.^[1]
