improvement of the Signal to noise ratio of lidar Echo Signal based on wavelet de noising technique
Optics and Lasers in Engineering, 2013Co-Authors: Zhirong Zhou, Shichun Li, Yufeng Wang, Yan Li, Hongwei WangAbstract:Abstract According to the characteristics of a Lidar Echo Signal contaminated by noise, especially in strong background light, an effective de-noising method of wavelets based on a soft threshold is proposed to reduce the Lidar Echo Signal noise and improve the Signal to noise ratio of system. The principles and methods of wavelet transforms and wavelet de-noising are utilized to de-noise the noisy Signals. Some preliminary simulations are carried out to reduce the noise of the simulated Signals in order to verify the feasibility of the de-noising method. In addition, using experimental data of the Lidar Echo Signals contaminated by noise in the strong background light, the de-noising range-square-corrected Signals and the retrieved aerosol extinction coefficient are obtained. The results show evidence of the de-noising effects and demonstrate that this method can effectively de-noise the noisy Lidar Signals in strong background light and achieve improvement in the Signal to noise ratio of system.
