Abstract

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.
