基于散射中心极化比的锥体目标姿态反演

从高分辨一维距离像（high range resolution profile，HRRP）出发，针对HRRP姿态敏感以及锥体目标识别中姿态获取困难的问题，推导分析了散射中心极化比与锥体目标姿态的关联关系，提出了基于散射中心极化比姿态反演的方法:利用散射中心参数估计模型对锥体目标不同极化下的宽带数据进行分析，分别提取其散射中心参数，同时计算散射中心参数的极化比，并与理论的极化比曲线进行匹配，最终获取目标的姿态角.基于球头锥的数值计算与极化特征提取结果验证了方法的有效性.利用此方法能够做到对目标姿态的快速反演，为进一步的目标识别提供支撑.

Attitude inversion of cone targets based on polarization ratio of scattering center

This article starts from the high range resolution profile(HRRP), on account of difficult problems in the characteristics of the sensitivity of the HRRP and the recognition of the target of the cone type attitude, analyzes the correlation between polarization ratio of scattering center and the target attitude. Scattering center parameter estimation model is used to extract the scattering center parameters of cone targets from the wideband data, such as amplitude and location of scattering center. And the amplitude polarization ratio of the extracted scattering center parameters is calculated, so as to match the theoretical polarization ratio curve and finally obtain the attitude angle of the target. The results of numerical calculation and polarization feature extraction based on spherical cone verify the effectiveness of the method, which provides a basis for further target recognition.
