Abstract：Feature parameters estimation for ballistic targets is the basis of target recognition. Because of the difficulty to estimate the precession and structure parameters of a cone-cylinder target jointly without prior knowledge of parameters, a new method for the cone-cylinder target’s precession and structure parameters estimation is proposed based on High Range Resolution Profile sequences (HRRPs). The HRRPs of the rotary symmetrical cone-cylinder target are simulated and analyzed in four attitude angle regions respectively based on static electromagnetic scattering data. The trace of each scatter in the HRRPs is researched in the common radar viewing aspect, and the relationship between the extreme value of three scattering centers’ relative positions in the HRRPs and the target’s parameters is built, then the precession and structure parameters are estimated simultaneously. Finally, the estimation results of feature parameters show that the proposed method is effective and adaptive.
