The Characteristic Inversion of the Mid-course Missile Based on the Ellipse Model

摘要

摘要: 针对弹道中段目标RCS序列识别问题，在分析其运动特性与电磁散射特性的基础上，结合传统的基于椭球体的目标形状反演模型，提出了一种新的利用RCS幅度相对于目标姿态角变化率反演弹道中段目标长短轴比值和目标相对于雷达视线姿态角的方法，克服了传统方法需要观测到目标RCS极大、极小值的缺陷。利用仿真和暗室测量的典型弹头类目标的RCS数据，验证了方法的有效性。

Abstract: This paper is for the identification from the RCS sequence of the Mid-course missile. On the base of analyzing its motion and electromagnetic scattering characteristic, a new method using RCS magnitude changes with respect to the object gesture angle for inversing the mid-course objects long-short axis ratio and gesture angle to the line of the radar is presented. Comparing with the traditional ellipse method, the new method overcomes the disadvantage of the necessity for the maximal and minimal RCS value of the object. The experiment results tested by the simulated and darkroom measurement of the representative missile object show the effectiveness of the method.
