Analysis of Millimeter Wave Scattering Characteristics and Imaging Effect Factors of Human Biological Tissue

Millimeter wave has good penetration, and millimeter wave imaging technology has made great development in recent years. Therefore, millimeter wave imaging technology has great commercial value in the field of security inspection. This paper studies the electromagnetic parameters of human body and the algorithm of active millimeter wave imaging. The equivalent composite dielectric constant of human body at 94GHz was obtained through derivation, and the algorithm formula of two-dimensional millimeter wave holographic reconstruction imaging based on the principle of synthetic aperture radar was deduced, which provided a theoretical basis for the research of active millimeter wave imaging applied in security inspection field.
