摘要
针对堤防工程质量检测现状,研究了探地雷达检测方法在堤防检测中的应用,采用小波分析法分析了雷达实测数据,根据信号与噪声的小波系数性质不同,采用相应规则对含噪信号进行小波阈值去噪。实例应用结果表明,去噪效果较好,有利于实测资料的分析解释。
According to the current research situation about the quality detection of dikes, GPR applications in the quality detection of dikes are discussed in detail. Wavelet analysis is applied to analyze the radar data. Based on the difference of wavelet coefficients between signal and noise, SNR is improved by adopting wavelet threshold denoising method to deal with the signal in terms of the relevant rules. The analysis of GPR data shows that the effect is good and it benefits analysis and explanation of GPR data.
