AbstractHaiyang-2B (HY-2B) is the second ocean dynamic environment satellite of China and was launched on launched on October 26th, 2018. Radar altimeter is one of HY-2B's main payloads and mainly used to provide sea surface height (SSH), significant wave height (SWH) and sea surface wind speed measurements. In this paper, the range noise level of HY-2B radar altimeter is estimated and compared with Jason-2 and Jason-3 altimeters. The noise level of HY-2B radar altimeter for an SWH of 2 m is estimated to be 1.38 cm, which is lower than those of Jason-2 and Jason-3 (1.60 cm). Sea level anomaly (SLA) power spectra analysis also shows that the HY-2B altimeter has low noise level with respect to Jason-2 and Jason-3. Therefore, the HY-2B radar altimeter has the potential to provide sea surface height measurements of high precision.
