A new approach based on least square fit method is proposed to estimate damping. Noise resistance of the proposed method and half-power bandwidth method are analyzed and compared by plenty of simulations with different signal-to-noise ratios (SNR). The proposed method is more accurate and stable than half-power bandwidth method in all SNRs, especially when the noise level is high. If , the proposed method should be used for damping estimation instead of half-power bandwidth method. A damping
