Abstract

To alleviate the effect of noise on lightning signal data processing, a denoising method based on Double Density Dual Tree wavelet is proposed. General lightning signal and real lightning signal are denoised with this method respectively. Experiment results show the proposed method can effectively alleviate noise of lightning signal and it is superior to the traditional wavelet threshold. Compared with denoising method based on hardware, the proposed method is more economical, convenient and practical.
