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. ***

9712012刘这笔赠款为康涅狄格大学的浅层地球物理项目提供部分支持，用于购置额外的探地雷达天线、一个工作站和一台个人电脑。将购买三个频率分别为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情况。计算机将用于数据采集以及随后的反演和建模。在一项配套的地球物理提案的研究支持下，PI将开发一种非线性频率依赖模型，用于土壤和浅层的高分辨率探地雷达层析成像，并将研究雷达信号在非均匀地层中的传播。改进的探地雷达层析成像技术对具有环境意义的问题(即绘制受污染的地下水羽流图)的潜力值得继续发展这项地球物理技术。***
