一种基于AIS数据的机载雷达系统误差实时自动标校方法OA

In maritime surveillance,airborne radar systems often suffer from inaccurate target positioning due to system errors,which affects navigational safety and management efficiency.In view of the problem,this paper proposes a real-time automatic calibration method for airborne radar system errors combined with Automatic Iden-tification System(AIS)data.In the proposed method,AIS targets and radar-detected targets are matched through spatiotemporal alignment and data association algorithms to establish the corresponding relationship.Then,the AIS data is used as a benchmark,and the convergence condition control of multidimensional feature error thresh-olds is employed to realize the real-time correction for the track data errors of radar-detected targets.Experimental results verify the effectiveness of the proposed method.The test design and verification analysis conducted with the field-collected AIS data and radar data demonstrate that this method can effectively detect and correct system errors automatically.
