| Abstract | Compared with conventional radar altimeter (CRA), synthetic aperture radar altimeter (SARAL) is a new generation radar altimeter with better height precision and along-track spatial resolution. As using synthetic aperture technique, SARAL data processing and waveform model are very different from CRA. To verify the performance and the data processing algorithm, an airborne experimental system of SARAL is developed. The experimental system was installed in Y-12 aircraft, and some valid data was obtained in October 2014. The echo data with SAR mode is obtained in the experiment and the echo data of CRA mode is extracted from SAR mode data. The two modes have the same observation targets and error sources and, then, their height measurement precisions are comparable. The results indicate that the rangemeasurement precision of SARALis improved about 1 times. The difference of the significant wave heights from the SAR mode data and CRA mode data is negligible. |
