| Abstract: |
| With the development of remote sensing technology, the SAR satellite network appears, which can not only improve the observation frequency, but also improve the observation accuracy by combining the remote sensing detection ability of different data sources. This paper introduces the development status of remote sensing observation technology based on satellite network. The research progress of marine dynamic environment monitoring and marine target monitoring based on satellite network has been summarized. In the aspect of remote sensing monitoring of marine dynamic environment, the synchronous data obtained by multi-satellites can complement each other, and then obtain the information of marine dynamic environment parameters which cannot be detected by a single satellite. In the aspect of remote sensing monitoring of marine targets, multi-satellite combination can realize the leap from traditional single image ship recognition to multi image ship tracking, and improve the tracking and monitoring ability of marine dynamic target. With the rapid development of satellite remote sensing constellation, satellite network observation will become a development trend in the feature. It is urgent to further develop multi-source remote sensing data processing technology and improve the comprehensive marine application ability. |
