WAVEFORM ANALYSIS OF TOPEX/POSEIDON SATELLITE ALTIMETER OVER LAKE
湖泊范围内TOPEX/Poseidon卫星测高波形分析

The altimeter waveform data of satellite TOPEX/Poseidon over Hulun lake are analyzed. It is proved that satellite altimeter waveforms over lake have ocean-like characteristics. Most of the altimeter waveforms are peaks or spikes during the frozen period in winter, while the wave energy is lower than that in summer owing to the influence of snow and ice covering the lake surface.
