Adding skewness, a new second order echo model was derived according to the one of Amarouche. With respect to characteristics of HY-2A altimeter waveforms, six retracking schemes were derived with singular value decomposition filtering and different parameters wanted based on maximum likelihood estimation; After processing the data with five-parameter scheme, the proper skewness of elevation probability distribution function of scattering points was 0.15. According to comparisons between significant wave height from the six schemes and that from buoy, Jason-1 and HY-2A IDR, the accuracy of the schemes were analyzed, and the scheme MLE4_SVD (singular value decomposition filtering is conducted before retracking) was the better one for retrieving significant wave height from HY-2A altimeter retracking.
