Precision Comparison and Airborne Experiment Validation between SAR Altimeter and Conventional Altimeter

摘要

摘要: 合成孔徑雷達(dá)高度計(jì)是目前測(cè)高精度最高的新一代衛(wèi)星海洋雷達(dá)高度計(jì)，它將孔徑合成的思想引入到傳統(tǒng)高度計(jì)中來(lái)，測(cè)高精度比傳統(tǒng)高度計(jì)提高了1倍。該文在對(duì)合成孔徑雷達(dá)高度計(jì)與傳統(tǒng)雷達(dá)高度計(jì)的測(cè)量精度進(jìn)行比對(duì)研究的基礎(chǔ)上，提出了機(jī)載試驗(yàn)數(shù)據(jù)比對(duì)處理方法，首次通過(guò)機(jī)載試驗(yàn)的方法驗(yàn)證了合成孔徑高度計(jì)比傳統(tǒng)高度計(jì)測(cè)量精度提高約1倍的結(jié)論。

Abstract: Synthetic Aperture Radar ALtimeter (SARAL) is a new generation radar altimeter and has the best height precision now. As using synthetic aperture technique, the height precision of SARAL is improved by one fold. Based on studying the height precision of Conventional Radar Altimeter (CRA) and SARAL, a novel comparison method is developed to process the airborne flight experiment data. And the precision comparison result shows that the height precision of SARAL is increased by one fold.
