Abstract :
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.
