基于一维距离像序列的导弹目标进动参数估计

Precession parameter estimation of ballistic missiles based on HRRPs

鉴于弹道导弹尺寸、进动角和进动频率的准确估计有助于解决弹道导弹真假目标识别问题,以中段进动锥体目标为研究对象,建立了弹道导弹中段进动模型,推导了导弹目标一维距离像与导弹尺寸、进动参数之间的关系公式,并进一步分析了导弹目标进动对一维距离像的影响。在此基础上,提出了一种新的利用一维距离像序列变化进行导弹尺寸、进动角、进动频率参数估计的方法,进行的仿真试验验证了所提方法有效准确,为真假弹头识别提供了参考。

Because an accurate estimate of the size,precession angle and precession frequency of ballistic missile is very important to the ballistic missile target recognition,this article researches the precession cone target,establishes the missile precession model,derives the equation relationship among the HRRP,the size,precession parameter of missile,analyzes the impact of precession on the object.On this basis,we propose a new parameter estimation method which uses the changes of HRRPs.Simulation results verify the accuracy of the proposed method which provides the reference of target recognition.
