Track Segment Association Based on Maximum Conditional Expectation
LAI Zuomei
Abstract：Target maneuvering can easily lead to radar MTI track breaks and poor track continuity. In the case of target inten?sive conditions,it may even lead to misjudgment of the number of targets,which is very unfavorable for situation assessment and tactical decision-making. A novel ESM-assisted MTI turning maneuver target tracking adhesion algorithm is proposed. The ESM at?tribute information and MTI position information are used comprehensively to realize state estimation,maneuvering start end time identification and turning angle based on conditional expectation maximization(ECM)framework. Joint optimization of rates. The simulation results show that the introduction of ESM information can reduce the number of fault tracks and improve the track continu?ity by more than 15%.
