Real-time tracking plays a key roll for ocean radar altimeter (RA).In this paper
the maximum likelihood estimation (MLE) algorithm for RA is studied
including the scheme
the errors
and the realization.The α-β filter is also analyzed.A tracker for spaceborne RA based on sub-optimal maximum likelihood estimation (SMLE) was developed
and by which a lot of ocean echo signal curves were obtained successfully in the airborne flight experiment.This was the first time for China to obtain ocean echo signal curves based on SMLE
and it was a great step for China to develop spaceborne RA.
