Characteristic parameters estimation of procession cone target based on micro-Doppler

Cone target's time-frequency distribution is the symbols of micro-motion and structure information, for this matter, a characteristic parameters estimation method of procession cone target based on micro-Doppler is proposed. The theoretical micro-Doppler of procession cone target's scattering source is deduced, which is decomposed into the synthesis of many order harmonic components by descending power formula of trigonometric function, then the target tracking technology is introduced to gain different scattering sources' micro-Doppler, and a method to gain the characteristic parameters is proposed finally by the relation between the harmonic component and the characteristic parameter, which may offer some references for spatial cone target's recognition.
