A Compressed Sensing technique for multistatic three-dimensional millimeter-wave personnel screening

The design of an active three dimensional millimeter wave imaging system for personnel security screening using Compressed Sensing (CS) is presented in this work. The system is able to produce a high-resolution 3D reconstruction of the whole human body surface and reveal concealed objects under clothing. A CS technique is used to drastically reduce the number of sensors, thus simplifying the system design and fabrication and improving the reconstruction results over previous approaches. Representative simulation results showing good performance of the proposed system are provided.
