对卫星测高波形数据分类的聚粪分析方法进行改进，给出一个用于确定最佳聚类数的有效性指标。以台湾海峡的Topex／Poseidon测高数据为例，对近海测高波形进行分类研究，并分析各类波形的最优重跟踪方法，在此基础上提出近海测高波形重跟踪的自适应方法。对多个周期测高数据进行重跟踪试验，结果表明，自适应方法优于其他重跟踪方法，可显著提高近海测高数据的质量。%The cluster analysis method for satellite altimeterwaveform classification is improved. A cluster validity index is proposed for determining optimal cluster number. Coastal Topex/Poseidon waveform data over Taiwan Strait are classified using the cluster analysis method, Based on the study of the optimal waveform retracking approach for each waveform type, an adaptive retracking algorithm is developed and applied to several tracks in different cycles asa test. The results show that adaptive retracking method is superior to the others, Coastal altimeter data can be significantly improved using the adaptive retracking method,
