本文简要介绍了探地雷达（GPR）的成像方面。在三个调查领域进行了不同的实验，以证明地质雷达成像的地下材料的可行性。首先，获得位于砂池内部的电和尺寸不同的对象的GPR特征，并将其处理成聚焦图像。由此产生的图像显示，即使是具有固有的低水平回报的目标可以通过GPR定位。第二个实验的目的是通过地质雷达技术检测水从塑料管道泄漏。结果表明，泄漏周围的额外的水表现为图像中的反射区域，从而提供有关泄漏位置的信息。此外，对混凝土柱进行了探地雷达测量，以定位和成像柱内的箍筋。研究结果表明，探地雷达在混凝土柱箍筋位置和尺寸的测量分析中是可用的。
This paper presents a brief overview on the imaging aspects of ground penetrating radar (GPR). Different experiments in three fields of investigation are conducted to demonstrate the feasibility of GPR for the imaging of subsurface materials. First, the GPR signatures of electrically and dimensionally different objects located inside the sand pool are obtained and processed into a focused image. The resulted image reveals that even the targets which have inherently low-level returns can be located by GPR. The second experiment is aimed to detect the water leaks from the plastic pipes via GPR technique. It is shown that additional water around the leak manifest itself as reflecting regions in the image, thereby giving information about the leak location. Furthermore, the GPR measurement of concrete column is performed to locate and image the stirrups within the columns. The results dictate the usability of GPR for concrete column analysis in measuring the position and size of stirrups.
