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.

该提案的目的是开发对光学不透明但可被微波穿透的物体成像的方法。有很多种这样的材料，包括活组织，木材，陶瓷，塑料，服装，混凝土，土壤等，这个建议的重点是近场微波成像的物体具有复杂的内部结构。这一研究领域在生物医学成像、隐蔽武器探测和地下探测方面有重要应用。理论上，与远场测量相反，近场测量由于可以捕获更精细的形状细节而提供了更高图像质量的潜力。在实践中，这一潜力基本上仍未得到利用。
