摘要
该文简述了在反射系数为白噪声条件下探地雷达记录道中零相位子波的提取 ,并用提取的子波对探地雷达信号进行互相关滤波的方法原理及编写的相应的程序。应用所编程序对合成的水平层状探地雷达剖面和弯曲层状探地雷达剖面进行子波提取及互相关滤波处理。结果表明 :应用该文所介绍的处理方法不但能有效压制探地雷达信号中的随机干扰而且能精确确定反射波的起跳点。
The paper discusses the principle of zero-phase wavelet extracted from Ground Penetrating Radar (GPR) record at the base of coefficient of reflection being white noise and used to remove the random noise in the GPR signal with cross correlation filter. The corresponding program is made to process synthetically horizontal GPR profile and slalom GPR profile. The results demonstrate the cross correlation filter not only can suppress random noise in GPR signal but also confirm exactly the onset of reflection wave.
