| 摘 要： | 提出了基于聚类分析的多子波优化重定算法,即利用聚类分析对波形进行分类,然后在分类的基础上对每一聚类的波形分别采用β参数拟合算法和门槛算法对其进行重定,最后以误差平方和最小为依据选择最优的作为最后的结果。经过基于聚类分析的多子波优化算法重定后的卫星测高数据与验潮站数据进行了比较,发现该算法能在一定程度上改善近海卫星测高数据的精度,提高重定成功率,降低重定次数。

| Abstract: | A new retracking method based on multi-wave optimizition with cluster analysis is put forward in the paper. The clustered waveforms are retracked by β parameter and threshold method based on the classification with cluster analysis. The best result is chosen according to the minimum of error sum of square. It shows that the new method can improve the altimetry data precision, increase retracking success rate and reduce retracking number by comparing the retracked altimetry data and tide station data. |

| Keywords: | waveform retracking cluster analysis multi-wave optimizition tide station |
