摘要

与红外和可见光成像相比,被动毫米波成像具有更好的穿透性和隐蔽性等优点。因此,PMMW成像在人员安全检查中具有发展潜力。近年来,一些研究人员探索了偏振成像方法来提高系统性能。基于多极化成像的实测数据,分析了不同偏振图像下隐蔽目标的检测性能。此外,我们还定量比较了不同偏振模式、Stokes参数和线性偏振度(DOLP)下的接收机工作特性(ROC)曲线和目标对比度。结果表明,合理选择和融合偏振有利于充分发挥偏振成像的优势。

Concealed Object Detection Performance of Polarimetric Passive Millimeter-Wave Imaging
Compared with infrared and visible light imaging, passive millimeter-wave (PMMW) imaging has many excellent characteristics, such as better penetration and concealment. Therefore, PMMW imaging has the development potential in personnel security inspection. In recent years, some researchers have explored polarization imaging methods to improve system performance. Based on the measured data of multi-polarization imaging, this paper analyzes the detection performance of concealed objects in different polarization images. Furthermore, we quantitatively compare the receiver operating characteristic (ROC) curves and target contrast ratios of different polarization modes, Stokes parameters and the degree of linear polarization (DOLP). The results show that reasonable selection and fusion of polarization is conducive to giving full play to the advantages of polarization imaging.
