摘　　要：被动毫米波实时成像技术在许多领域有广阔的应用。本文介绍了被动毫米波实时成像技术的特点、应用前景、工作体制和发展现状,并以用于人体安检的、采用了综合孔径辐射计技术的被动毫米波实时成像系统为例,详细讨论了其工作原理、系统设计、成像算法及成像实验等关键技术内容。所研制的被动毫米波成像系统实现了24帧/秒的成像速度,以及6cm@3m的空间分辨率和1-2K的温度灵敏度。Real-time passive millimeter wave imaging technology potentially has wide applications in many fields. In this paper we give a full discussion on the specialties, application prospects, system architectures and development status of this technology. Taking the synthetic aperture radiometer imaging system as an example, we present in detail the system＇s im- aging mechanisms, system design principles, image formation algorithms and system imaging results. Our imaging system prototype realized good specifications of 24 frames/second of imaging rate, 6cm@ 3m spatial resolution and 1-2K temperature resolution.
