摘要
探地雷达的分辨率和地下电磁波的速度估计是探地雷达应用中两个重要研究课题 ,类似地震信号处理中的频率波数域偏移处理 ,本文提出将频率波数域偏移方法应用到探地雷达的成像和速度估计中来 。
Similar to the migration in frequency-wavenumber domain of seismic techniques, this paper presents an approach to focus on the ground-penetrating radar (GPR) data and estimate the electromagnetic wave velocity underground. To demonstrate the validity and feasibility of this approach, experimental GPR data are obtained with object buried in two different kinds of media. It is found that in homogeneous medium, this approach can be used to estimate the electromagnetic wave velocity underground and improve the imaging resolution.
