摘要
采用地质雷达探测地质体,很难直接从探测图像资料上获取目标体体积。这里基于频域雷达方程,提出了一种根据地质雷达探测影像宽度,电磁波长,以及目标体埋深等参数来计算散射截面,进而求取被测目标体等效体体积的计算模型,并将其应用于工程实例。计算结果表明,该模型准确可靠,是一种快速求取目标体体积的新思路。
In the detection geological body by ground penetrating radar, it is difficult to obtain directly the volume information of the goal body from GPR image. Based on the equation in frequency domain, This article proposes a mathematical model to compute the volume using the GPR data by the image width, the electromagnetic wave length and the goal body burying depth. The application of the method to a real case shows that it is accurate and reliable, and potential for the fast seeking goal body volume.
