摘要: |
针对弹道中段目标RCS(Radar Cross Section)序列识别问题,在分析中段目标电磁散射特性及运动特性的基础上,结合传统的基于球体、椭球体的目标几何特性反演模型,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二维几何尺寸的算法,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 of the RCS sequence of the mid-course missile. On the basis 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 object's two-dimensional length was presented. Compared 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. |
Keywords: radar cross section ellipse model mid-course missile inversion |
