  • Publication number: 20240111044
    Abstract: A system and method of threat detection using a pulsed polarimetric radar system using microwave range of frequencies in the electromagnetic spectrum. The system uses a radar principle to transmit and receive the scattered response from the target. A time pulsed upconverted frequency system is used to sample the target over a specified radio frequency (RF) bandwidth. The full 2-port scattering matrix (comprising all co and cross s-parameters) is captured using only one antenna with an OMT and delay lines, that represent the target. Several decompositions are used to describe the polarimetric signature of the target. The system uses polarimetric approaches to measure scattering properties of anomalous object concealed beneath clothing. The co-polarized and cross-polarized signals are analyzed to determine if a person is carrying an anomalous object beneath their clothing.
