合成孔径雷达高度计是目前测高精度最高的新一代卫星海洋雷达高度计,它将孔径合成的思想引入到传统高度计中来,测高精度比传统高度计提高了1倍。该文在对合成孔径雷达高度计与传统雷达高度计的测量精度进行比对研究的基础上,提出了机载试验数据比对处理方法,首次通过机载试验的方法验证了合成孔径高度计比传统高度计测量精度提高约1倍的结论。 |

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. |
