Abstract

MM-wave sensor operating at 94 GHz has been developed for detecting hidden objects such as weapons, explosives etc. It is based on a frequency modulated continuous wave (FMCW) and includes the two high gain horn-lens antennas integrated with a homodyne transceiver. The synthesized linear FMCW signal in K_u-band is multiplied by a factor 6 to generate the transmitted signal at 94 GHz. An intermediate frequency (IF) signals obtained in the output port of the mixer is employed for detecting hidden objects. Post detecting procedure was performed using and MatLab processing. Experiments have demonstrated an efficiency of the designed sensors for homeland security applications.
