星载SAR舰船检测技术及其在海洋渔业监测中的应用

Ship Detection with Spaceborne SAR and Its Application in Oceanic Fishery Monitoring

近年来,利用星载SAR数据对海洋舰船目标进行检测与监视的技术在很多领域得到了广泛的应用。海洋渔业资源保护和渔船监测就是其中的一个重要应用。目前为保护海洋渔业资源,促进其可持续利用,我国也正在进行利用星载SAR对渔船进行监测和管理的研究工作。对国内外公开发表的文献中关于星载SAR舰船检测方面的研究成果进行了总结,回顾并分析了舰船和舰船尾迹检测的常用方法,并说明了星载SAR舰船检测的一般流程。最后对国外利用星载SAR进行海洋渔业检测和资源保护方面的成功案例进行了介绍。希望能够从中得到有益的经验和启发,对我国在利用星载SAR进行海洋渔船监测和海洋渔业资源保护方面的研究和应用有所帮助。

In recent year, ship detection and monitoring techniques have been widely used in many areas, one of which is the fishermen monitoring and protection of marine resources. Researches of monitoring and managing the fishermen are being carried through in china in order to protect the marine resources. Ship detection techniques are introduced; the ship detection algorithms and wake detection algorithms have been both reviewed and analyzed. The stages of ship detection applications have been described as well. At the end of this paper, some successful applications, in which ship detection techniques based on spaceborne SAR are used in fishery monitoring and marine resource protection in foreign countries, are introduced. It is expected that some experiences and illuminations will be obtained from this paper, which will benefit our future works in fishermen monitoring and protection of fishery resources based on spaceborne SAR.
