智能雷场利用声学探测系统与无线传感网络来实现对打击目标的定位与跟踪,但在复杂多变的应用环境中,声学探测系统难以输出稳定的测量信息,容易出现探测丢包与误识别现象;由于雷场各地雷节点初始采样时间不同、采样周期不同和信息传输时延等原因,导致各节点的量测信息是非同步的;由于环境干扰,雷场组网通信时会发生网络阻塞,导致通信丢包。针对上述问题,提出一种基于平均一致性的分布式卡尔曼滤波算法。实验结果表明:在异步网络中,有明显探测丢失与误识别现象时,所提方法仍能对目标进行定位跟踪,定位精度可达到5m,满足智能雷场的定位需求,能够为智能雷场在复杂应用环境下的协同定位提供有效可行的解决方案。

Intelligent minefields use acoustic detection systems and wireless sensor networks to locate and track strike targets.However,due to the complex and varied application scenarios of minefields,as well as the susceptibility to interference,if the sound detection sensor is damaged or the detection effect is unstable due to environmental factors,the acoustic detection system is difficult to output stable measurement information,which can lead to detection packet loss and misidentification;Due to the different initial sampling times,sampling periods,and information transmission delays of each landmine node in the minefield,the measurement information of each node is asynchronous;Due to environmental interference,network congestion may occur during communication in minefield networks,resulting in communication packet loss.A distributed Kalman filtering algorithm based on average consistency is proposed to address the above issues.Each node analyzes the validity of measurement information,processes invalid measurements into a filter,obtains local posterior state estimates,and performs time alignment.The time aligned local posterior state estimates are fused based on the average consensus algorithm to obtain global posterior state estimates.The experimental results show that the proposed method can still locate and track targets in asynchronous networks with obvious detection loss and misidentification phenomena,with a positioning accuracy of up to 5m,meeting the positioning requirements of intelligent minefields and providing an effective and feasible solution for collaborative positioning of intelligent minefields in complex application environments.
