Investigation of polarization changing effect by hidden objects placed on a human body

Abstract

Possibility of identification of the hidden metal objects on a human's body based on changing of the reflected wave polarization sharp edges and vertexes of the object is considered. The matrix equation for the main and cross-polarizations amplitudes is formulated. Results of measurements are given in special installation. It is shown that amplitude of cross-polarization of the reflected signal can serve for indication of the hidden metal objects.
