Abstract：Due to the range-Doppler coupling effect of the LFM signal, the micro-Doppler caused by the micro- motion targets will also bring the bias detection range. Take the even rotational speed target as an example, the change of this bias detection range with time obeys the sinusoid, and this bias is large enough for the narrowband tracking radar. A new detection and estimation algorithm for the character of micro-motion based on the narrowband tracking information is proposed in this paper. The simulation result and the dynamic measure date of precession target in microwave anechoic chamber, which are designed according to the typical parameters of the tracking radar for the special targets, validate the conclusion of this paper and the effectiveness of detection and estimation algorithm.
