Multi-altimetric Data Processing Approaches in Shallow Water

The data quality of altimeter in shallow sea area are worse than that in deep sea area, this mainly because the tide in this area is affected by so many unexpected factors, such as complicated coast line, submarine topography and the water transportation from the inland river, and the altimeter measurements themselves are also affected by marine dynamic and land reflection. The precision and resolution of the solution of the average sea surface could be largely improved by combining several kinds of altimeter data,this consequently help us to improve the ability of monitoring sea surface and inversing the water driving dynamic mechanism in shallow sea area.In this paper,some approaches are presented on combination of several kinds of altimeter data.The data processing approaches are systematic investigated in the aspect of extracting average and time change sea surface information.By culling out time independent bias from each kind of altimeter data,sea surface time change datum is constructed.Then multi altimeter data are put into one dynamic system for sea level monitoring
