    Abstract
  • Micro-motion feature is one of the crucial features used for ballistic target recognition. Aimed at the model of cone-shaped target, a novel algorithm based on hybrid-scheme radar network combining wideband radar with narrowband radar is proposed to extract the micro-motion parameters. First, on the basis of analyzing the micro-Doppler change rule of the equivalent scattering centers on the precession cone-shaped target in detail, each scattering center in different system radar echoes is matched and identified by utilizing the micro-Doppler sum-difference ratio. Second, the associated systems of equations of micro-Doppler information are established, and parameters including the precession angle, radius of undersurface and height of cone-shaped target are extracted jointly. Furthermore, comparative study on the relationship between parameter estimation accuracy and error change of curve parameter extraction is made. Finally, the simulation results show that even though errors occur in curve parameter extraction, the parameter estimation accuracy of target is still enough.
