Ground penetrating radar have so many advantage, therefore applied very extensive. But now it still exist some proportion to waiting for improvement, for example, distinguishing the GPR diagram primar ily stays in the foundation of the artificial naked eye distinguish and handcraft identify. Therefore it is beneficial to us to understand the electromagnetic wave spreading regulation, and scoop out much more useful information from the GPR wave inside, through forward simulate the familiar penetrating object in physical.

地质雷达具有如此多的优点，故应用十分广泛；但是目前地质雷达亦还有待改进之处，如雷达图像的识别主要还停留在人工的肉眼和手工的基础上；所以对常见探测对象的物理正演模拟，有助于我们了解电磁波的传播规律，挖掘雷达波中更多有用信息。
