摘要
对均匀大气脉冲激光散射回波信号降噪方法进行研究。对回波信号频谱进行分析,并对低通滤波与自适应滤波对激光雷达信号处理效果进行对比,采用信噪比这一指标对信号的处理效果进行评估。
The denoising method of laser scattering echo signals for the uniform atmosphere is discussed. Based on the analysis of the frequency spectrum of signals, the effects evaluated via SNRs of low-pass and adaptive filters on the signal processing of lidars are compared.
