Influencing factors on re-tracking accuracies of SAR altimeter ocean power waveforms

Using the along track processing and delay correction, a Synthetic Aperture Radar (SAR) altimeter has better retrieved accuracies of the geophysical ocean parameters than conventional radar altimeters (CRAs). The retrieved accuracies of a SAR altimeter are relevant to the shape of ocean echo wave an...

Summary:Using the along track processing and delay correction, a Synthetic Aperture Radar (SAR) altimeter has better retrieved accuracies of the geophysical ocean parameters than conventional radar altimeters (CRAs). The retrieved accuracies of a SAR altimeter are relevant to the shape of ocean echo wave and the number or averaged pulses and the effective number of looks. In order to get the high precisions, the errors that influence the waveform should be eliminated. This paper analyses the influencing factors and give the results that how these factors influence the precision. How to correct these factors is also given in the paper.
