面向人体安检的毫米波转台成像实验

摘要

Two millimeter wave imaging schemes based on front-view mode and oblique-view mode are presented. A pair of sending and receiving antennas are utilized to scan target along the circumference. The millimeter wave imaging experimental platform is composed of vector network analyzer,horn antenna and high precision turntable. In order to validate the effectiveness of the two schemes and the corresponding wave-number domain algorithms, a series of objectives inversion imaging based on experimental platform are accomplished, and good experimental results are obtained. The feasibility of two kinds of millimeter-wave personnel surveillance is proved by the experiment results.%提出2种基于前视和斜下视圆周扫描的毫米波人体安检方案,该方案采用1对收发分置天线沿圆周扫描,利用矢量网络分析仪、喇叭天线和高精确度转台搭建了毫米波成像实验平台.为了验证2种方案及相应的波数域算法的有效性,通过毫米波转台实验对多个目标反演成像,并得到了良好的实验结果.实验结果表明,本文提出的2种毫米波人体安检方案都具有一定的可行性.
