Abstract

Abstract

The multi-angle characteristic of netted radar is helpful in obtaining the actual space structure of ballistic targets. In this paper, the echo model for precession targets with vanes is established. Based on the model, the rate of change of micro-Doppler for different scattering centers are analyzed, and the micro-Doppler information is extracted. Then the nonlinear least-square fitting is introduced to obtain the amplitude and phase information of scattering centers. Amplitude information of scattering centers at the conical point obtained from radars is used to estimate micro-motion characteristics and parameters of coordinate transformation. According to the distinctions among different projection components of scattering centers under different perspectives, scattering centers of fins are matched, and the instantaneous space coordinates are calculated to reconstruct the targets. Finally, simulations verify the effectiveness of the proposed method, and the influence of micro-motion parameters and SNR (Signal to Noise Ratio) on reconstruction results are analyzed.
