Abstract 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.
