Imaging of the shallow subsurface has been an area of intense research activity in recent years, fueled, in part, by the need for detailed knowledge of the near surface. This information is required not only for the environmental assessment of the contaminated subsurface in the remediation of buried waste sites, but also for shallow resource exploration and geotechnical engineering. Under favorable conditions, Ground Penetrating Radar (GPR), an electromagnetic sounding technique, provides detailed subsurface information to depths of 30 meters or more beneath the ground surface. This project details the acquisition of a state-of-the-art GPR system to enhance the field laboratory capabilities of the Geophysical Engineering Department. The acquisition of a GPR system provides the following: a method for site investigation that provides high-resolution images of the subsurface, a unique educational tool that enhances the teaching of fundamental concepts of electromagnetic wave propagation and digital signal processing, opportunities to apply basic field skills using the system in a full-scale field project, and a facility to promote undergraduate research. Students in the Geophysical Engineering and Geological Engineering Programs take 6 weeks of a combined geology/geophysics field course. Three weeks of this course are devoted to geophysics. This course provides an opportunity for students to gain field expertise using equipment commonly employed to make geophysical measurements. As a result, this course represents a chance for students to gain field experience using GPR. Moreover, GPR is a topic already included in several other courses. The acquisition of a GPR system allows the information discussed in these courses to become more relevant by providing hands-on use of this instrumentation by the students.

近几年来，浅层地下成像一直是一个激烈的研究活动领域，部分原因是需要详细了解近地表。这一信息不仅是在补救掩埋废物场时对受污染的地下进行环境评估所必需的，而且也是浅层资源勘探和岩土工程所必需的。在有利的条件下，探地雷达（GPR），一种电磁测深技术，提供详细的地下信息，深度为30米或更深的地面以下。 该项目详细介绍了购置最先进的探地雷达系统，以提高地球物理工程部的现场实验室能力。获得一个探地雷达系统提供了以下内容：现场调查的方法，提供高分辨率的图像的地下，一个独特的教育工具，加强电磁波传播和数字信号处理的基本概念的教学，机会，应用基本的现场技能，使用系统在一个全面的现场项目，并设施，以促进本科生的研究。 地球物理工程和地质工程专业的学生需要6周的地质/地球物理综合实地课程。这门课有三个星期是专门讲物理学的。本课程提供了一个机会，让学生获得现场专业知识，使用常用的设备，使地球物理测量。因此，本课程为学生提供了使用GPR获得现场经验的机会。此外，地质雷达是一个主题已经包括在其他几门课程。GPR系统的收购允许在这些课程中讨论的信息变得更加相关，通过提供动手使用这种仪器的学生。
