摘　　要：机载GMTI地面动目标跟踪的难点在于选择合适的目标运动模型和滤波算法,一般常用的单模型有CV、CA、Singer和当前统计模型(CS);常用的多模型为IMM(交互式多模型)及VS-IMM(变结构多模型)。本文研究了几种常用的单模型和多模型以及KF、EKF、UKF滤波算法,并进行了各种模型及滤波算法的仿真实验,最后给出了选择模型和滤波算法的建议。Aitborne GMTI ground moving target tracking difficulty lies in the choice of the target model and the approproate filtering algorithm,commonly usede model of CV,CA,Singer and the current statistical model CS,multi model commonly used for IMM and VS-IMM,this paper has studied several single model and multiple model commonly used,and KF,EKF,UKF filtering algorithm,and the simulation experiments of various models and filtering algorithm,finally gives the proposed selection model and algorithm of the GMTI moving target tracking.
