摘　　要：本文选取与海洋二号(HY-2)卫星高度计同步的Jason-1和Jason-2有效波高数据以及同步的浮标数据对HY-2卫星高度计观测的结果进行验证,结果表明HY-2观测的有效波高存在0.3—0.4 m的误差;通过HY-2数据和同步的浮标数据的拟合得到HY-2数据的校准关系式,并比较校准后的HY-2有效波高数据与Jason-1和Jason-2数据,表明校准后的HY-2数据能够更好地反映海面的真实状况。The HY-2, which was launched on August 16, 2011, is the first microwave marine remote sensing satellite developed by China. In this paper, the data of Significant Wave Height （SWH） measured by satellite altimeter HY-2 were compared with the data observed by satellite altimeter Jason-land Jason-2 as well as the data measured by buoys. It was found that there was a systematic error of 0.3--0.4 m between SWH obtained from HY-2 and other altimeters and buoys. The comparison indicated that there was a linear relationship between the data of HY-2 and buoys, which could be used to calibrate SWH measured by HY-2 to better reflect the real marine situation. Comparisons show that the results are good and HY-2 altimetry data work well with other satellite altimetry data.
