| Summary: | Active millimetre-wave (mm-wave) imaging techniques and systems have been widely investigated and developed, due to their ability to detect personal carried concealed weapons and other contraband, at airports and other secure locations. Up to date, several imaging configurations have been tested or proposed for active mm-wave personal security imaging system by different institutes, and each one focuses mainly on one configuration. To have visualised data or figures of different imaging system configurations, here, the authors build the simulation model of each imaging system for Feko software. Comparisons of different configurations to image the same object are provided based on simulation. The transmitting antenna number, receiving antenna number, and the reconstruction images are presented.
