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。
In this paper, the principle of extracting the zero-phase wavelet in the GPR track with white noise and the cross-correlation filtering of the GPR signal with the extracted wavelet is briefly introduced and the corresponding program is written. The programmed wavelet transform and cross-correlation filtering are applied to the synthesized horizontal layered GPR profile and the curved layered GPR profile. The results show that applying this method can not only effectively suppress the random interference in GPR signals but also accurately determine the starting point of the reflected wave.
