| 加拿大Radarsat雷达卫星只有7种工作模式,是专门为海冰业务监测设计的。1999年1月我们预订和获取了两模式雷达卫星数据,对我国渤海海冰进行了监测研究,两种模式各有优点,ScanSAR模式可用于对整个渤海地区的全面监测,而利用宽幅的高分辨率图象可得到渤海海冰的详细特征结果。同时在研究过程中对辽东湾海冰和沿岸冰进行了实地观测,为解译提供了重要依据。 |
| The Radarsat satellite-borne SAR of canada has seven kinds of working mode, which is designed especially for operating monitoring of sea ice. it’s used widely in military science, earth science, and especially in the field of oceanography. We have subscribed two kinds of the seven for monitoring and studying sea ice in the Bobal Sea of China. Each of them has it’s own advantage. The ScanSAR mode can be used in monitoring of the whole Bobal Sea. And the WideA mode can be used to get the detail of the characteristic of sea ice. At the same time, an experiment on-board was carried out for observing the sea ice of the Liaodong Bay. It provides important information for the interpretation of the sea ice. In addition, the simultaneous NOAA and GMS data and other relative data were also used for comparison study. At last, we give some proposal for the use of SAR data in our research in the future. |
