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。 Radarsat Radarsat has only seven modes of operation and is designed specifically for the monitoring of the sea ice business. In January 1999, we ordered and obtained two-mode radar satellite data, and conducted a monitoring study on sea ice in the Bohai Sea. Both modes have their own advantages. The ScanSAR model can be used for comprehensive monitoring of the entire Bohai Sea region. However, Resolution images give detailed characterization of the sea ice in the Bohai Sea. At the same time, the on-the-spot observation of sea ice and coastal ice in Liaodong Bay during the research process provided an important basis for interpretation.
