    摘要
  • 摘要: 目标微动及结构参数的获取有助于弹道目标的识别。准确获得进动锥体目标散射特性的时频分布(TFD)、一维距离像及二维逆合成孔径雷达(ISAR)像分布是获取锥体目标微动及结构参数的关键。分析了进动锥体在窄带及宽带条件下的目标散射特性,总结了锥体目标强散射源在时频分布、距离像序列和ISAR像序列中的理论表现形式,并分析了存在锥面镜面散射时锥体目标散射特性,构建了进动锥体目标电磁回波仿真方法及微波暗室动态测试系统,通过仿真及测试数据得到了典型条件下锥体目标的散射特性,对比表明仿真及测试结果均与本文散射特性理论分布相一致,说明了本文所提散射特性理论分布与散射特性分析方法的正确性,可为分析弹道目标散射特性研究提供参考。

     

    Abstract: The micro-motion and structural parameters of the ballistic target play an important role in ballistic target recognition. And correctly acquiring scattering characteristics of precession targets is essential to obtain these parameters, such as time-frequency distribution (TFD), range profiles and inverse synthetic aperture radar (ISAR) images. Scattering characteristics of the precession cone target under narrowband and wideband are analyzed, especially on the case where the specular scattering exists, and the theoretical expressions of TFD, range profiles and ISAR images with respect to strong scattering centers of the target are given briefly. In addition, a dynamic measuring system in anechoic chamber was established to collect the electromagnetic response from the precession target. The simulation and experimental results are verified with theoretical deductions, and so as for the feasibility of the proposed model and imaging algorithm.
