探地雷达速度谱估计的实验研究

Experimental Study on GPR Velocity Spectrum

电磁波在地下媒质中的速度估计是探地雷达应用研究的重要课题,本文基于地震探测的共中心点的速度谱理论,提出利用点目标速度谱来估计探地雷达脉冲电磁波在地下媒质中的传播速度,并用实验数据验证了本方法的有效性。

Based on velocity-spectrum theory used in geophysics, this paper presents an approach to estimate ground-penetrating radar (GPR) velocity underground. Similar to the common mid-point (CMP) method in seismic, the approach calculates the velocity spectrum of the point object in GPR. Finally, the validity of this approach is experimentally proved.
