Study on Precessional Targets Dimension Estimation Based on HRRPs

摘要

摘要: 利用高分辨距离像估计目标尺寸是弹道导弹中段防御雷达目标特征提取和识别的重要途径。该文提出了一种在目标进动条件下，利用多幅高分辨一维距离像进行中段弹道目标真实长度估计的方法。推导了目标1维高分辨距离像长度与弹道目标真实长度、进动参数之间的函数关系，建立了1维距离像长度的观测模型，采用最大似然估计法实现了目标长度的估计。最后给出了基于仿真数据和某弹头实测数据条件下的尺寸估计仿真结果，验证了所提方法的有效性。

Abstract: Estimating targets dimension using High Resolution Range Profile (HRRP) is an important means of character extraction and target recognition of ballistic missile mid-course defense radars. In this paper, a new estimation method of middle-course ballistic missiles dimension using multiple HRRPs under the condition of precession is presented. The function of the targets HRRP length and the targets real dimension and precession parameters is derived, and the measurement model of HRRP length is constructed, based on which a maximal likelihood estimation method is adopted to realize the estimation of the targets dimension. Finally, the simulation results of dimension estimation based on both simulation data and measurement data of one real warhead are given, which validates the validity of the method.
