摘要
通过分析电磁波在地下介质中的传播规律,介绍了探地雷达监测地下目标体的基本原理。设计实验方案,对地下常见目标体进行探测,由于不同介质对电磁波的反射差异,对其波形图进行分析,通过对波形图的分析找出图像差异,通过实验可以获得不同目标体的波形图差异,并且通过标定获得了电磁波在介质中的传播速度,编写软件提取轮廓找出图像差异识别目标物,并通过双层走时与标定的传播速度算出目标物的位置。通过实验验证了该方法确定目标物位置的可行性。
By analyzing the propagation law of electromagnetic wave in underground medium, the basic principle of ground penetrating radar monitoring underground target is introduced. The experimental design, the underground common target detection, due to the reflection of different media on the electromagnetic wave difference, the waveform analysis, through the analysis of the waveform identify the image difference, can be obtained through experiment waveform of different target, and through the calibration of the velocity of electromagnetic wave propagation in the medium the preparation of the software to find the difference image contour extraction target recognition, and through double traveltime and calibration of the propagation velocity of the target position is calculated. The feasibility of this method in determining the target position is verified by experiments.
