基于AIS的对海雷达多目标融合跟踪方法
A Method of Multi-Target Fusion and Tracking for Sea Surveillance Radar Based on AIS
摘要
Abstract
For the great difficulty of data association and low tracking accuracy in the intensive target tracking of sea surface,a track fusion method based on automatic identification system (AIS) information is proposed in this paper.Firstly,the fusion coefficients are calculated according to the measured value of AIS and the measurement noise level of radar,which can ensure rationality of fusion data.Then the data association of double gates is made by use of the fusion track for the measured value of radar,which can optimize the data association method,improve the confidence level of target measurement value,and reduce the influences of false alarm and clutter.Thus,the track robustness and the tracking accuracy are improved.Finally,the validity and superiority of the method is proved by simulation data and actual measurement data.关键词
