9309775 Lee The objective is to conduct research for the development of synthetic-aperture tomographic imaging techniques and the implementation of microwave and acoustic prototype systems capable of quantitative NDE of civil structures and materials. The long- term goal of this research is the realization of high-resolution, cost-effective, portable imaging devices for accurate visualization of quantitative characterization of the condition of civil structures such as bridges, roadways, harbors, dams and buildings. These imaging devices can be used for not only existing structures for maintenance or safety considerations, but also for newly constructed facilities for verification and inspection purposes.

目标是开展合成孔径层析成像技术的发展以及能够定量无损检测土木结构和材料的微波和声学原型系统的实施研究。本研究的长期目标是实现高分辨率、高性价比、便携式成像设备，用于精确可视化定量表征土木结构（如桥梁、道路、港口、水坝和建筑物）的状况。这些成像装置不仅可用于现有结构的维修或安全考虑，也可用于新建设施的核查和检查目的。
