Removing the ground penetrating radar direct wave via 2-D directional continue wavelet tansform & the choice of mother wavelet

  • 摘要: 简单介绍了二维连续小波变换的基本理论,详细分析了二维连续有向小波变换去除直达波的基本原理,对比了二维Cauchy小波及Morlet小波函数的性质,进而讨论了实际工程应用中小波函数的选择问题。通过实际工程探地雷达资料检验了该方法的有效性。
    Abstract: After a brief introduce of the theory of 2-D continue wavelet transform, the method is deeply studied to remove the direct wave by means of the 2-D directional continue wavelet transform technique. Furthermore, the resolving power of wavelets is discussed. The 2-D Cauchy wavelet is chose as mother wavelet for it’s effective computation compared with 2-D Morlet wavelet. The efficiency of the method has been demonstrated by practical GPR data.
