Abstract

Millimeter wave imaging technology has received a lot of attention in recent years. It has been widely applied in aircraft landing guidance system, dangerous substance inspection, plasma tests and human carry on safety inspection. It can be applied in many areas in the future. This paper studies an active millimeter wave focal plane imaging system. Among the theory and key techniques of millimeter wave imaging, the optical imaging system is designed and automatic scanning, automatic data collection and image processing are implemented. In the experiment system, the automatic focal plane scanning of the receiver antenna array, data collection around the imaging spots of the 94GHz millimeter wave, automatic imaging and image optimization are carried out at the computer. The experiment verifies the practicability of the design of the diffractive lens and the detection of hidden objects.
