摘　　要：提出了一种新的基于二代小波的消噪算法,可以有效地消除激光回波信号中的噪声.仿真结果表明,该算法可以有效地提高信噪比,降低激光回波信号中所含有的噪声,与传统小波去噪算法相比,该算法计算简单,适合于实时处理.A novel signal denoising algorithm based on second generation wavelet transform is proposed, which can effectively eliminate the noise in the laser radar echo signal. Simulation results show that the algorithm can improve signal-noise-ratio（SNR） and reduce the noise of the laser radar echo signal, compared with the traditional wavelet denoising algorithm, the algorithm is simple, suitable for real time processing.
