Millimeter-waves can be used to detect and identify objects e. g. those hidden by clothes on a person's body. For this purpose, several approaches have been developed. When specular reflections are accessed by the imaging system, the resulting millimeter-wave images are mainly determined by their high amplitude response. Additional contributions to the scattered field arise for measurement configurations with slanted illumination. As an example the different contributions of a metallic plate using the Uniform Theory of Diffraction (UTD) are shown for different measurement setups. Taking advantage of the different spatial distribution imaging systems can be tailored by a selection of a proper configuration of the aperture for the imaging of total objects or object inhomogeneities such as edges and corners only.
