海上目标雷达与AIS航迹时空匹配方法
Spatiotemporal Matching Method Between Maritime Target Radar and AIS Track
摘要
Abstract
Aiming at the spatio-temporal mismatch between radar and AIS(Automatic Ship Identification System)tracks of maritime targets,a method of interpolating AIS track data to align radar target tracks according to the characteristics of maritime track movement after spatial alignment is proposed,which can solve the spatio-temporal mismatch between ra-dar and AIS tracks and minimize interpolation errors.According to the advantages of ship course change rate combined with speed course method and interpolation extrapolation method,the method automatically selects the best interpolation method according to different track characteristics,and realizes the automatic interpolation and space-time alignment of the radar and AIS track points of maritime targets.The simulation results show that the proposed method can automatical-ly match and select the best interpolation method for the complex movement of the marine target,effectively reduce the error,and realize the spatio-temporal matching between radar and AIS track.关键词
