影响星载卫星雷达高度计测高精度的因素很多，其中大气干对流层延迟、大气湿对流层延迟、大气逆压延迟、电离层延迟以及海况偏差直接影响海表面高度计算精度。本研究开展了海洋二号卫星雷达高度计上述误差修正算法研究，并利用国外较为成熟的Jason-1/2和Topex/Poseidon（T/P）卫星雷达高度计数据产品对海洋二号卫星雷达高度计使用的误差校正算法进行验证。结果表明，海洋二号卫星雷达高度计数据处理时使用的误差校正算法均可满足精度要求。

There are many factors affecting the height accuracy of satillite radar altimeter. The dry troposphere delays, wet troposphere delays, invert barometer delays, ionosphere delays, and sea state bias influence the computational accuracy directly. The error correction algorithms for the HY-2A satellite radar altimeter were conducted in this research. And, these algorithms were vertified using the more mature foreign satellite data such as Jason-1/2 and T/P. The results show that the HY-2A error correction algorithms can meet the accuracy requirements.
