【摘要】 对飞行目标跟踪所涉及到的运动模型与滤波算法研究现状进行了综述,着重分析了非机动和机动这两类运动模型的特点和几种典型模型的适用条件,介绍了相应的线性和非线性滤波算法;在此基础上针对实际工程中遇到的利用非均匀时间间隔离散衍生信号求解目标状态向量的问题,基于非线性最优化理论提出了一种高效实用的反演计算方法,该方法取得了良好的目标状态向量分析结果。更多还原

【Abstract】 The status in quo movement models and filter algorithms come down to target’s tracing are summarized.The characteristics of non-maneuverable and maneuverable movement model and their application conditions are analyzed.Corresponding linear and non-linear filter algorithms are introduced.To achieve the solution of state vectors according to unequal interval sampled discrete derived signal,a backward algorithm based on non-linear optimization theory is proposed,which has been applied in practical engineering successfully.更多还原
