| 摘 要： | 基于非洲东海岸MAYG站2020年年积日268～366的信噪比（SNR）数据开展GNSS-IR（global navigation satellite system interferometric reflectometry）监测海平面高度研究，并与Dzaoudzi验潮站的实测潮位进行对比。结果显示，BDS-GEO不适用于岸基测高；BDS-MEO的监测精度优于BDS-IGSO和GPS。

| Abstract: | Based on the SNR(signal-to-noise ratio) data of doy 268-366 at the MAYG station on the east coast of Africa in 2020, we carry out the GNSS-IR(global navigation satellite system interferometric reflectometry) sea level monitoring study. We compare the results with the measured tide level of Dzaoudzi tide gauge station. The experimental results show that BDS-GEO is not suitable for shore-based altimetry. The monitoring accuracy of BDS-MEO is better than that of BDS-IGSO and GPS. |
