Development of networked collaborative detection technology for underwater mobile platforms

在水下网络中心战思想的指引下,无人水下航行器、鱼雷兵器等水下移动平台网络化协同探测是必然的发展趋势。该文阐述了协同探测网络拓扑结构、网络节点空时统一的关键问题;针对水声复杂信道给通信组网带来的困难,给出了协同探测网络中时变信道自适应复合调制、信道自适应接入机制和移动通信同步的初步方案;并探讨了协同探测的一些关键问题和应用策略,包括跨平台传感器的信息融合、尺度目标的方位分布特征提取以及鱼雷自导多目标协同跟踪。提供的一些计算机仿真结果初步显示了网络化协同探测的优越性。

Guided by the theory of underwater network centric warfare (UWNCW), it is an inevitable trend to develop networked cooperative detection for unmanned underwater vehicle (UUV), torpedo weapon and other underwater mobile platforms. This paper expounds some key problems about network topology, time synchronization and node self localization in the underwater cooperative detection system. In view of the difficulties of communication network in the complex underwater acoustic channel, it gives some preliminary schemes of the cooperative detection network, including adaptive compound modulation to time-varying channel, adaptive channel access and synchronization of underwater mobile communication. The paper also explores some key problems and application strategies of cooperative detection, such as, cross-platform sensor information fusion, feature extraction of azimuth extension of scale target, and multi-target cooperative tracking. Some computer simulation experiments show the advantage of networked collaborative detection.
