Abstract

Due to rather low absorption in fabric materials of clothes, millimeter band electromagnetic waves can serve for customs service as additional source of operative and remotely obtained information concerning any irrelevant discontinuities located on human body under clothes, likewise about dimensions and types of such discontinuities. One significant problem is appearing when passive (radiometric) millimeter wave systems for customs control are under development. The question is what radiothermal brightness contrasts may be expected for various objects from different materials located on human body and under changed conditions of observations, as far as some capabilities of the method need to be evaluated and specifications to the indicated monitoring systems generated. In this paper a set of measurements was carrying out in brightness contrasts measurements at M-band frequency range for samples from various materials located on human body
