Although ranges in the terahertz frequency spectrum are decreasing due to atmospheric attenuation, near-range applications are of great interest for industrial applications. This paper summarizes and compares the main technological approaches and concepts.enTerahertzTHzImagingRadarMIMODDC::500 Naturwissenschaften und Mathematikconference paper
