Abstract在轨实时跟踪处理是海洋雷达高度计的关键环节,本文系统地研究了应用于海洋雷达高度计跟踪器的最大似然估计算法的原理,算法误差分析,以及α-β滤波器的工作机理.在此基础上研制了基于准最大似然算法的星载海洋雷达高度计跟踪器,该跟踪器在机载飞行试验中获得了成功,在国内首次获得了基于准最大似然算法的海洋回波曲线,为我国星载海洋雷达高度计的发展奠定了重要的基础.
Other AbstractReal2time 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.Theα2βfilter 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.
