摘要
建立合适的机动目标运动模型是目标跟踪的基础。概述几种机动目标模型特点及相互之间的关系,分析反舰导弹末端"蛇行机动"弹道模型,结合其控制指令及机动性能,给出反舰导弹的末端机动模型,并构建机动频率函数对机动频率进行自适应调整,优化了机动目标"当前"统计模型的系统参数。在给定的初始条件下进行仿真试验,仿真结果表明:改进的算法适应能力强,能有效提高"当前"统计模型的跟踪性能。
Some kind of maneuvering target models feature and relation of each other are summarized,and 'snake-wriggling maneuver' model trajector for anti-ship missile is analyzed.considering its steering order and capability of maneuver,it gives out the terminal maneuver model.The algorithm adjusts the maneuvering frequency adaptively through the maneuvering frequency function,optimizes the system parameter about current statistical model.At the given initial conditions,simulation experiments are carried ...
