    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.
