9818137DanielsThis award supports research that is concerned with significantly improving the recognition and definition of buried objects with multi-component ground penetrating radar (GPR) measurements in three dimensional space by utilizing the vector properties of electromagnetic energy, which is generally referred to as polarization. The experiments conducted with this support are designed to address the following problems related to GPR polarization: 1) determine the nature of the polarized GPR electric field from anennas that are designed as linear electric dipoles, 2)develop the basic methodology for determining antenna patterns from experimental measurements on simple geometric objects (sphere, plane and cylinder), 3) develop the means to measure, process, display and interpret multi-component polarization measurements, and 4) establish a library of scattering matrices for some common targets. The testing will be conducted using physical models located at the Ohio State University, and a finite difference time domain computer modeling software. Results of these studies will be used to improve the resolution and definition of three dimensional displays of GPR data.***

9818137 Daniels该奖项支持的研究是有关显着提高识别和定义的埋地物体与多分量探地雷达（GPR）测量在三维空间中通过利用电磁能量的矢量属性，这通常被称为极化。 利用这种支持进行的实验旨在解决与GPR极化相关的以下问题：1）从被设计为线性电偶极子的天线确定极化GPR电场的性质，2）开发用于从简单几何对象上的实验测量确定天线方向图的基本方法（球面、平面和柱面）; 3）开发测量、处理、显示和解释多分量偏振测量的方法; 4）建立一些常见目标的散射矩阵库。 将使用位于俄亥俄州州立大学的物理模型和有限差分时域计算机建模软件进行测试。 这些研究的结果将用于提高探地雷达数据三维显示的分辨率和清晰度。
