Abstract：According to the characteristics of satellite altimeter waveforms, a new classification of radar altimeter waveforms, called minimum distance, is presented. The method based on the principle of dynamic cluster analysis can efficiently classify the radar waveforms by using moving minimum Euclidean for similarity index. Topex/Poseidon coastal waveforms across Taiwan strait are applied to comparatively analyze the classification results of pulse peakiness and Beta5, and the feasibility of the classification is verified, and K value of reasonable coastal altimeter waveforms classification is determined.
