摘要
太赫兹近场多输入多输出合成孔径雷达(MIMO-SAR)技术具有在保证分辨率同时降低阵元数量的优势，在人体安检中有重要的研究和应用价值。该文首先介绍了应用在人体安检领域的太赫兹近场MIMO-SAR技术系统现状，将典型系统进行了归纳和对比；其次介绍阵列设计，对典型面阵列的指标特性进行了仿真对比；介绍典型的成像算法和加速方法，比较成像算法的图像重构速度。最后对发展进行了展望。
Abstract
Terahertz near field MIMO-SAR technology has advantage of reducing the number of arrays while ensuring resolution, thus it has important application in human security inspection. This paper firstly introduces the application of terahertz near field MIMO-SAR technology in human body security inspection, then introduces the system composition, imaging algorithm, and finally makes a prospect of development.
