Focused on security application, experiments are carried out to research on passive millimmeter wave imaging. The personnel concealed object detection model is discussed, and a prototype of conically scanning single pixel imaging system is realized and introduced. The control experiment is carried out using the prototype, and the images with and without the concealed object are respectively obtained. A nonlinear brightness transform function is also designed to process the obtained images. The experiment result demonstrates the capability of the realized PMMW imaging system for security application, and the designed brightness transform function could effectively enhance the intelligibilityof the images.
Keywords:Millimeter wave imaging; Concealed object detection; Passive detection; radiometer system
