Generating high resolution images is one of the most important capabilities of imaging systems for security applications. To achieve this goal, electrically large apertures are required, thus involving a large number of measurement samples or receivers, which leads to long acquisition times. Compressed Sensing techniques are one way to reduce the number of samples required for accurate image reconstruction...
This work develops compressed sensing techniques to improve the performance of an active three dimensional (3D) millimeter wave imaging system for personnel security screening. The system is able to produce a high-resolution 3D reconstruction of the whole human body surface and reveal concealed objects under clothing. Innovative multistatic millimeter wave radar designs and algorithms, which have...
