The use of electromagnetic waves at microwave and millimeter-wave (mm-wave) frequencies in imaging has been growing rapidly in the last two decades with applications in security screening, biomedical imaging, nondestructive testing, and the inspection of goods and packages. The nonionizing nature of the radiation renders microwave and mm-wave imaging (MMI) safe for humans and, thus, attractive, especially for frequent imaging of living tissue and humans. At the same time, the radiation penetrates many materials, which are optically opaque: e.g., fog and foliage, soil and living tissue, brick and drywall, wood, fabrics, and plastics. Importantly, modern MMI systems offer compact and relatively low-cost hardware due to advancements in high-frequency microelectronics.

使用微波测量进行傅里叶空间图像重建：实时微波和毫米波成像之路


过去二十年来，微波和毫米波 (mm-wave) 频率电磁波在成像中的应用迅速增长，应用于安全检查、生物医学成像、无损检测以及货物和包装检查。辐射的非电离性质使得微波和毫米波成像 (MMI) 对人类来说是安全的，因此具有吸引力，特别是对于活体组织和人类的频繁成像。同时，辐射会穿透许多光学不透明的材料：例如雾和树叶、土壤和活体组织、砖块和干墙、木材、织物和塑料。重要的是，由于高频微电子技术的进步，现代 MMI 系统提供了紧凑且成本相对较低的硬件。
