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...
