Acquisition of Ground Penetrating Radar Antennas and Computing Facilities for the Near-Surface Geophysics Programat the University of Connecticut

小行星9712012 这笔赠款为康涅狄格大学浅层地球物理学项目购置额外的探地雷达（GPR）天线、一个工作站和一台个人电脑提供部分支持。 将购买三个频率为25、200和1000兆赫的探地雷达天线，以研究探地雷达信号在各种地质和结构环境中的衰减。 计算机将用于数据采集和随后的反演和建模。 PI将与一项伴随的地球物理学建议的研究支持一起，开发一个非线性频率依赖模型，用于土壤和浅层地壳的高分辨率GPR层析成像，并将研究雷达信号通过非均匀地层的传播。 改进的探地雷达层析成像技术对环境问题的重要性（即绘制受污染的地下水羽流）的潜力保证了这种地球物理技术的继续发展。 ***

9712012 Liu This grant provides partial support for acquisition of additional ground penetrating radar (GPR) antennas, a workstation and a PC for the shallow geophysics program at the University of Connecticut. Three GPR antennas at frequencies of 25, 200 and 1000 MHz will be purchased to examine the attenuation of GPR signals through various geological and structural environments. The computers will be used for data acquisition and subsequent inversions and modeling. Together with research support from a companion geophysics proposal, the PI will develop a non-linear frequency dependence model for high resolution GPR tomography of soils and the shallow crust and will investigate the propagation of radar signals through inhomogeneous strata. The potential of improved GPR tomographic techniques to problems of environmental significance (i.e. mapping contaminated groundwater plumes) warrants continued development of this geophysical technique. ***
