中文摘要：
为了克服噪声对闪电信号数据处理的影响,提出了一种基于双密度双树小波变换的闪电信号去噪方法。采用该方法分别对标准闪电波和实测的闪电信号进行了去噪研究,实验结果表明双密度双树小波变换能够有效滤除闪电信号中的噪声,效果优于传统的小波阈值法,而且比硬件去噪更加经济、方便和实用,值得进一步的推广和应用。
英文摘要：
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.
