一种基于目标点迹关联的舰载多雷达数据融合系统

A shipborne multi-radardata fusion system based on target plot correlation

导航雷达是保证舰船航行安全的重要传感器,由于舰船空间结构比较复杂,为了消除单部导航雷达的观测盲区,舰船上会在不同位置安装多部导航雷达。本文设计了一种工程化的新型舰载多雷达点迹融合系统,给出了系统实现方法,并结合数据仿真分析了融合系统的性能。采用本文提出的点迹融合系统方案,只需较小的计算和通信代价,就可以解决单部导航雷达观察盲区内目标的连续跟踪问题,而且多部雷达观察范围内数据融合后的目标跟踪性能优于单部雷达设备。

Navigation radar is an important sensor to ensure the safety of ship navigation.Due to the complicated space structure,multiple navigation radars are installed in different locations onboard to eliminate the observation blind zone of a single navigation radar.A new shipborne multi-radar plot fusion system is designed,the implementation method is given,and the performance of the fusion system is analyzed through data simulation.The multi-radar plot fusion system with low computation and communication cost can track targets in the blind zone continuously,and its target tracking performance is superior to that of a single radar.
