Abstract (in Japanese) (See Japanese page) 
(in English) In order to improve the quality of object recognition characteristics in passive millimeter-wave (PMMW) imaging,a method using a dielectric pipe occupied by cooling water placed on focus line of a parabolic reflector is proposed. Uniform aperture distribution of a parabolic reflector with low brightness temperature is obtained by adjusting the position of cooling water tube. Furthermore, the back-lighting PMMW imaging using a cooling tube with parabolic reflector behind a human body and the forward-lighting PMMW imaging using them illuminating a human body and objects are performed. It is shown that the contrast of a human body and the background in PMMW images are improved in the case of the back-lighting.
The contrast of human body and conducting scatterers such as a conducting plate and a conducting sphere are also improved in the case of the forward-lighting.
