摘要

质心在目标上的位置是弹道中段目标的重要进动特征,也是目标的质量分布特征,可用于识别弹头和诱饵.针对旋转对称目标,提出了基于窄带雷达回波相位特性的质心位置估计方法.首先,选取目标对称轴上的任意点作为质心位置参考点,定义相应的质心位置参数,并构造以该点为相位参考中心的全姿态散射系数模板;然后,对窄带雷达回波采样序列进行相位匹配变换,搜索匹配函数的最大值,从而得到质心位置参数的估计值.仿真结果表明了该方法的有效性.

Abstract

The position for the centroid at the target is important precession and mass distribution characteristics of a ballistic target in midcourse, and can be used to discriminate between warheads and decoys. A centroid position estimation method is proposed based on the phase signature of the narrow-band radar echo for the rotationally symmetric target. An arbitrary point at the target axis of symmetry is selected as the reference point for the centroid position. The corresponding centroid position parameter is defined, and the all-attitude scattering coefficient template is constructed with the point as the phase reference center. The phase matching transform is performed on the sample series of the narrow-band radar echo, and the centroid position parameter is estimated by searching for the maximum value of the matching function. Simulation results show the effectiveness of the proposed method.

Key words： motion estimation; parameter estimation; phase matching; missiles; radar target recognition
