摘要	Lidar is an efficient tool for remote monitoring, but the effective range is often limited by signal-to-noiseratio (SNR). By the power spectral estimation, we find that digital filters are not fit for processing lidarsignals buried in noise. In this paper, we present a new method of the lidar signal acquisition based onthe wavelet trimmed thresholding technique to increase the effective range of lidar measurements. Theperformance of our method is investigated by detecting the real signals in noise. The experiment resultsshow that, our approach is superior to the traditional methods such as Butterworth filter
