| 摘 要： | SAR卫星的组网观测，较之于单卫星工作方式，不仅能够提高观测频率，还能挖掘SAR的多模式探测能力。本文介绍了SAR卫星组网的遥感观测技术发展现状，并总结了基于卫星组网的海洋动力环境监测和海上目标监测研究进展。在海洋动力环境遥感监测方面，多SAR卫星联合获得的同步数据能够互为补充，提高海洋动力环境信息的探测精度；在海上目标遥感监测方面，多卫星联合能够实现从传统的单星目标检测到跟踪的跨越，提高海上动态目标的跟踪监测能力。

| 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. |
