  • Since the concept of Global Navigation Satellite Reflected Signal (GNSS-R) was proposed, GNSS-R has been widely used in remote sensing, and has been used in sea surface height measurement, sea surface wind field inversion, sea ice detection and other aspects. This article mainly introduces the application and research progress of GNSS-R remote sensing technology in sea surface height measurement. Highlights the research progress based on signal-to-noise (SNR) ratio data measurement methods, and briefly describes the theory and signal processing methods involved in SNR ratio data measurement methods and according to the current research progress. The future development direction of sea surface altimetry is prospected.
