Waveform retracking of Topex/Poseidon altimeter in Chinese offshore
浅海区域Topex/Poseidon测高卫星数据波形重构方法

Based on the character of T/P satellite altimetry return waveform, we present a method to retrack the waveform data and determine the retracking correction with function approach, then improve the precision of altimeter observations in offshore.*#For the South China Sea region,*#we have processed four cycles T/P altime- ter waveform data. Compared with near time tide gauge data, the precision of the post-processing sea level height is greatly improved. We conclude that this method can be used to determine sea level height with high precision in offshore regions.
