Tools and techniques for microwave imaging and sensing

微波成像和感测为研究感兴趣区域的未知结构或性质提供了非侵入性工具。 这些技术用于不同材料具有不同电磁（EM）特性的情况，或者可以通过EM特性变化来识别材料的变化的情况。 其应用范围广泛，包括用于检查路基的探地雷达、医疗微波成像和材料含水量表征。 所有这些应用程序的共同点是需要可靠和有效地收集数据，以及将这些数据转化为有意义的结果的手段。拟议研究计划的主要目标是开发一种灵活的微波成像系统，使用多种低成本传感技术提供敏感和特定的图像。

Microwave imaging and sensing provide non-invasive tools for investigation of the unknown structure or properties of regions of interest. These techniques are used in scenarios where different materials have different eletromagnetic (EM) properties, or where changes in a material may be identified through EM property variations. The diverse range of applications includes ground-penetrating radar for inspection of roadbeds, medical microwave imaging and characterization of water content of materials. Common to all of these applications is the need for reliable and effective collection of data, as well as a means for translating these data into meaningful results. The main objective of the proposed research program is to develop a flexible microwave imaging system that provides sensitive and specific images using multiple, low-cost sensing technologies.
