基于电磁波的地下目标体探测实验设计OA

Electromagnetic wave is highly theoretical and difficult to understand,therefore an electromagnetic wave underground target detection experimental system is designed based on Lab VIEW.The functions of precise antenna positioning,automatic real-time data acquisition and imaging are realized.In the operation of the system,high-frequency electromagnetic waves are transmitted to the ground via a transmitting antenna,with the echoes reflected from underground received by a receiving antenna subsequently.On the basis of the differences in the electrical properties of underground media,the collected echo signals are processed and analyzed systematically.By analyzing the results of numerical simulation and physical simulation,the electromagnetic response characteristics of the underground target can be mastered,and the spatial location,structure and burial depth of the underground medium can be inferred.This experimental system is convenient for students to understand and master abstract concepts,stimulate students' enthusiasm for learning and interest in scientific research and exploration.
