为了提高被动毫米波（PMMW）成像中物体识别特性的质量，提出了一种在人体和物体方向形成零点的新方法。利用置于抛物柱面焦线上的冷却水介电管进行前向归零被动毫米波成像。实验表明，PMMW 图像中人体与导电散射体（例如导电板和导电球体）之间的对比度因具有抛物柱面的冷却介电管的存在而得到改善。
In order to improve the quality of object recognition characteristics in passive millimeter-wave (PMMW) imaging, a new method to form a null in the direction of human body and objects is proposed. The forward-nulling passive millimeter-wave imaging using a dielectric tube occupied by cooling water placed on focus line of a parabolic cylinder are performed. It is shown experimentally that the contrast between human body and conducting scatterers such as a conducting plate and a conducting sphere in the PMMW images is improved by the presence of cooling dielectric tube with parabolic cylinder.
