利用数值模拟仿真探地雷达地下障碍物探测

探地雷达方法没有严格的场地要求,只需满足适用该法的地球物理条件即可,方法简便,效率高,应用范围逐渐拓宽。但在复杂场地条件下,雷达剖面上异常体的判断比较困难。而利用数值模拟方法,结合现场条件,对目标体进行数值模拟计算,参照模拟的结果进行对比解释,将有助于异常体的判断,提高解释的准确性。文中结合探地雷达在地下障碍物探测工作中的实际应用,通过数值模拟初步判断地下障碍物在雷达图像上的反映,进而对采集的资料进行相关分析,取得了良好效果。

Detection of Underground Barrier Using Ground Penetrating Radar by Numerical Simulation

There is no strict site requirement for ground penetrating radar method,only satisfying geophysical conditions applicable for this method.Radar method is simple and efficient and its aplication range has been gradually expanded,but under complex site conditions,it is difficult to judge abnormal bodies on radar section.Combined with site conditions,the object is calculated using numerical simulation and explained compared with simulated result,which is favorable to judge abnormal bodies and improve precision of explanation.Combined with actual application of ground penetrating radar in underground barrier detection,this paper preliminarily determines reflection of underground barrier on radar image through numerical simulation and thus analyzes the collected data,which has achieved better effect.
