摘　　要：雷达和船舶自动识别系统(AIS)是保证现代船舶航行安全的重要导航设备。针对1部雷达和1部AIS得到的目标航迹进行融合,提出1种基于模糊理论的雷达/AIS目标数据融合方法,采用模糊数学中的正态隶属函数法来进行航迹相关,数据融合则采用参数加权方法,并将融合后数据进行多项式拟合,用以提高导航数据信息的精度与可靠性。通过仿真实例验证了此方法的可行性与有效性。Radar and automatic identification system（AIS）is essential to ensure safe navigation of ships of modern navigation equipment.A radar and AIS target data fusion algorithm based on fuzzy theory is proposed in this article,which adopts normal membership function for track correlation.In the data fusion process,fit the polynomial function with the data after using the weighted parameters method.It will integrate radar and AIS information to improve the navigation accuracy and reliability of data.Simulation shows this method demonstrated the feasibility and effectiveness.
