| 摘 要： | 以贝加尔湖为例,利用Jason-2测高卫星4年(2008~2012)GDR数据,经过误差改正与数据编辑,通过分析贝加尔湖月水位异常时间序列,得到了贝加尔湖湖面高变化的季节性规律;通过分析贝加尔湖半年水位异常时间序列,得出了贝加尔湖湖面高变化的周期为1年;计算结果表明,利用卫星测高技术对内陆湖泊湖面高变化进行监测具有一定的可行性。

| Abstract: | The GDR data of Jason-2 from 2008 to 2012 over Lake Baikal are analyzed through some data editing rules and geographical corrections for monitoring the water level changes.The lake level variation of half-yearly and monthly are calculated.The lake level variation of monthly shows that,the water level changes with seasonal pattern.The lake level variation of halfyearly shows that,the period of water level changes is 1years by using FFT method,which provides the ability for satellite altimetry to monitor the lake level variations. |
