中文摘要
翻译
这项提议的目标是开发对光学不透明但可被微波穿透的物体进行成像的方法。这类材料种类繁多,包括生物组织、木材、陶瓷、塑料、服装、混凝土、土壤等。本方案的重点是对具有复杂内部结构的物体进行近场微波成像。该领域的研究在生物医学成像、隐蔽武器探测、地下探测等领域有着重要的应用。理论上,近场测量,而不是远场测量,由于有可能捕捉到更精细的形状细节,因此有可能获得更高的图像质量。在实践中,这种潜力在很大程度上仍未得到开发。
英文摘要
THE OBJECTIVE of this proposal is the development of methods for the imaging of objects which are optically opaque but are penetrable by microwaves. There is a great variety of such materials including living tissues, wood, ceramics, plastics, clothing, concrete, soil, etc. The focus of this proposal is on the near-field microwave imaging of objects with complex internal structure. This line of research has important applications in biomedical imaging, concealed-weapon detection and underground detection. In theory, near-field measurements, as opposed to far-field measurements, offer the potential for higher image quality due to the possibility of capturing much finer shape details. In practice, this potential has remained largely untapped.
