Abstract
The main problem of the conventional radar altimeter echo model for big antenna mispointing angle is analyzed
and then an echo model containing the sea surface skewness coefficient is derived.This echo model can be used for retracking the echo wave when the antenna mispointing angle is big.Finally
the model is used to process the data of the HY-2A radar altimeter during the stage of adjusting satellite attitude
and the results are compared with the measurements of the buoys of NDBC(National Data Buoy Center).It shows that the model can give more accurate results.
