Abstract

A micro-Doppler (mD) frequency estimation method for the precessional ballistic target is proposed in this paper. Based on the derived theoretical mD frequency model of the precessional ballistic target, we use the time-varying autoregressive (TVAR) method to estimate the frequency components contained in the returned signal and the results are rearranged to eliminate the association errors. Experimental results based on the electromagnetic computation data are presented, which demonstrates the algorithm performance under different SNR conditions and with the different target motion parameters.
