摘要
针对导弹防御系统中的目标识别问题,该文研究弹道中段目标的2维几何特征反演方法。基于中段目标的特殊物理结构,分析了进动锥体目标在雷达径向投影尺寸的变化规律,建立了中段目标2维几何特征与其径向尺寸序列的映射关系,进而提出一种基于HRRPs的2维几何特征反演方法,能够稳定反演出中段进动目标在不同姿态下的2维几何特征。通过电磁计算数据和暗室测量数据验证了所提方法的有效性和稳定性。
This paper focuses on Two-Dimensional （2D） geometric feature inversion method of midcourse targets, serving for the target recognition problem of ballistic missile defense system. Based on the figuration characteristic of midcourse targets, the regular pattern of radial dimension is analyzed with respect to different intervals, the mapping relationships between HRRP under various target attitudes and the 2D geometric feature of target are established, then an 2D geometric feature inversion method for midcourse targets based on HRRPs is proposed accordingly. The method can estimate stably the 2D geometric feature of midcourse targets during the midcourse flight, which is verified by the simulation experiments with electromagnetic computed data and measured data in anechoic chamber.
