基于水下传感器网络的目标跟踪技术研究现状与展望

Underwater target tracking has extensive application value and important strategic significance in the development and utilization of marine resources, and national security defense. Target tracking technology via underwater sensor networks (USNs) has become a new research hotspot for its wide coverage, long observation time and real-time fusion. This paper gives a review of the basic ideas, research progresses, applications, and limitations of those key technologies of target tracking via USNs. It is mainly discussed from the following respects: the construction status of USNs, system composition and classification, target tracking system model, single target tracking technoligies, multi-target tracking technoligies, and energy efficiency optimization measures. Furthermore, this paper not only points out the main challenges of researches of target tracking via USNs, but also prospects the future development direction of the field.
