小波变换在探地雷达弱信号去噪中的研究
Study of wavelet transform in ground penetration radar weak signal denoising
摘要
Abstract
Based on the theory that the wavelet coefficients can signify the wavelet functions and analyze the degree of signal approxima⁃tion, by superimposing the wavelet coefficients of different scales we compare nine kinds of wavelet functions and find that Mexican hat wavelet can be used to erase high frequency noise in GPR signals and amply effective signals, thereby providing basis for the judgment on suspected abnormal location by adopting the traditional data processing method to process the GPR signals.关键词
