Özet

Recently, studies on the remote detection of dangerous objects on the person have gained importance with increased security problems. Therefore, the use of passive millimeter waves in security systems is increasing because they are harmless to health and can penetrate clothes. In this study, a compact low-noise radiometric sensor (LNRS) that can be used to view hidden objects on the person was constructed. The LNRS can be arrayed thanks to its small size and ease of use, and can be used in imaging applications thanks to the 0.24 K resolution obtained. In addition, a passive millimeter imaging system (PMMWI) was developed to obtain images with the LNRS. The PMMWI system, which is realized in a quasi-optical structure, can be used in many experimental studies thanks to its compact structure.
