The objective of this research is to perform exploratory research to assess the potential capability of wide-band radar in imaging FRP-confined concrete systems. The proposed work will scientifically test a novel idea of focusing through data processing of multiple scattering microwave signals in distinguishing different damage levels under the FRP layers. Capabilities including the optimization of resolution, penetration, and computing time will be tested. Owing to the novelty of the study, we will bring together the expertise from the Department of Civil and Environmental Engineering, Department of Electrical Engineering and Computer Science, Research Laboratory of Electronics, and Lincoln Laboratory of the Massachusetts Institute of Technology.Successful completion of this project would lead to an enormous scientific impact and lead us to the next phase of developing new imaging technologies for FRP-confined concrete systems. Such technologies are urgently needed, and would revolutionize industrial practices and better help ensure public safety. In view of the novelty and impacts of the subject, this proposal is considered suitable for an SGER grant.

本研究的目的是进行探索性研究，以评估宽带雷达对玻璃钢约束混凝土系统成像的潜在能力。拟议的工作将科学地测试一个新的想法，通过数据处理的多次散射微波信号，区分不同的损伤程度下的FRP层集中。将测试包括分辨率、穿透力和计算时间优化在内的能力。由于这项研究的新奇，我们将汇集来自土木与环境工程系，电气工程和计算机科学系，电子研究实验室，和马萨诸塞州理工学院的林肯实验室。该项目的成功完成将产生巨大的科学影响，并使我们进入下一阶段，开发新的玻璃钢成像技术-约束混凝土系统 这些技术是迫切需要的，将彻底改变工业实践，更好地帮助确保公共安全。鉴于这一课题的新奇和影响，我们认为这一建议适合获得SGER补助金。
