微波和毫米波频率的近场成像可用于各种各样的应用，包括隐蔽武器检测、穿墙和内壁成像、探地雷达成像、雷达截面分析和材料的非破坏性评估。在太平洋西北国家实验室（PNNL），已经开发了各种新的成像技术用于许多这些应用。这些技术利用宽带全息波前重建方法，并已发展到优化图像质量和分辨率。本文将总结这些技术，并显示成像结果的几个有趣的应用领域。
Near field imaging at microwave and millimeter wave frequencies is useful for a wide variety of applications including concealed weapon detection, through-wall and inner-wall imaging, ground penetrating radar imaging, radar cross section analysis, and non-destructive evaluation of materials. A variety of novel imaging techniques have been developed for many of these applications at the Pacific Northwest National Laboratory (PNNL) . These techniques make use of wideband holographic wavefront reconstruction methods, and have been developed to optimize the image quality and resolution. This paper will summarize several of these techniques and show imaging results for several interesting application areas.
