摘　　要：在分析目标运动特点的基础上,提出了一种新的基于跟踪-微分器的机动目标估计模型。该估计模型与卡尔曼滤波算法相结合,能够在动态过程完全未知的情况下估计出目标运动参数,且估计模型简单,物理意义明确,能够适应于目标的各种机动行为模式。仿真结果表明,具有跟踪-微分器结构的估计模型不但具有很强的适应性,而且能够获得满意的估计精度。Based on the analysis of the characteristics of target motion,a new maneuvering target estimation model based on a tracking-differentiator（TD） is presented.By combining this model with the Kalman filter,the movement parameters can be obtained,even though the dynamics of the maneuvering target is unknown.The model is simple and has clear physical meaning.It is applicable to all kinds of target maneuvering modes.Simulation results show that the new estimation model with construction of TD is with strong adaptability and can obtain the satisfying estimation precise.
