As these waves pass through materials, they are partially reflected and diffracted at physical discontinuities (changes in dielectric constant or electrical conductivity) and detected by a receiving antenna. By analyzing the time and intensity of the reflected signal, information on the nature, depth, and geometry of the objects or layers passed through can be obtained.[\/vc_column_text][vc_empty_space empty_h=&#8221;3&#8243;
