空中大机动目标跟踪算法研究

摘要

To solve the problem of high maneuvering target tracking in the missile terminal guidance,the interacting multiple model (IMM) and cubature Kalman filter (CKF) algorithm are applied to the missile guidance.The high maneuvering target is modeled and analyzed in the 3D space,and the corresponding missile guidance model and seeker measurement model are established.The IMM and CKF methods are designed to track the target.The simulation verifies the accuracy of the algorithm for tracking aerial high maneuvering target,and the results show that this algorithm has certain advantages in realtime,which is suitable for onboard computer.%为了解决在导弹末制导阶段对空中大机动目标的准确跟踪问题,将交互式多模型(IMM)及容积卡尔曼滤波(CKF)算法应用于导弹寻的制导中.首先,在三维空间中对大机动目标进行建模分析,并建立相应的导弹制导模型及导引头测量模型;其次,结合IMM模型与CKF方法设计了目标跟踪算法;最后,通过仿真验证了该算法对空中大机动目标跟踪的准确性,结果表明该算法在实时性方面也具有一定的优势,适合用于弹载计算机.
