Abstract Based on the echoes with micro-Doppler signatures, a method is proposed to estimate target frequencies and amplitudes. Model echoes as multi-harmonic micro-Doppler one in order to obtain the connection between target amplitude ratio and frequency domain peak ratio and the relationship between maximum Doppler frequency and target amplitudes. Thus, the method estimating target vibrational parameters is deduced. The method is applicable to the target detections as long as the echoes has multi-harmonic micro-Doppler signatures. The theoretical validity is illustrated with simulation results.
