摘　　要：弹道导弹的进动特性是弹道目标识别的重要依据之一。针对弹头目标的中段进动参数估计问题,提出了基于成像质量的进动参数估计算法,并实现了搜索参数的有效降维。算法合理挖掘了弹头的结构特性和散射特性,只需通过对进动角的一维搜索就可得到进动参数的估计,实现了弹头尺寸未知条件下的进动参数估计。仿真实验结果验证了算法的有效性。The feature of ballistic missile＇ s precession is one of the important substances for ballistic object recognition. Based on the parameter estimation of midcourse warhead＇ precession, an algorithm is proposed for the parameter estimation based on imaging quality, and the parameter dimension of search is reduced. This algorithm reasonably analyzes the warhead＇ s structure feature and electromagnetic scatter- ing features. The parameters estimation of precession can be obtained by only searching precession angle＇ s one dimension, which realizes the parameter estimation of precession without knowing warhead＇ s size. Simulation results show that the algorithm is effective.
