Abstract: Imaging systems and associated methods are described. According to one aspect, an imaging system includes processing circuitry configured to: access radar data for a plurality of sampling points at a plurality of different locations of an imaging aperture, and wherein the radar data results from the transmission and reception of electromagnetic energy via an antenna array with respect to a target imaging volume; access a plurality of different weightings that correspond to different ones of the sampling points of the imaging aperture; focus the radar data of the sampling points to generate an image of the target imaging volume; and wherein the processing circuitry is configured to use the different weightings of the sampling points to focus the radar data of respective ones of the sampling points.

Abstract: Systems and methods described herein provide systems for scanning an individual to identify hidden objects carried by the individual. The systems and methods employ imaging masts with transmitters and receivers of electromagnetic radiation. First and second imaging masts transmit and receive radiation on first and second scan paths, respectively, about a central point. The first and second scan paths are in a mirror-image arrangement with respect to the central point. The geometry of the imaging mast scan paths enables the use of multistatic reconstruction algorithms and improved data acquisition as compared to conventional systems and methods.

Abstract: A dual detector includes a detection head having a platform and an inductive sensor that is mounted on the platform and includes a transmitter coil and a separate receiver coil. The transmitter coil and the receiver coil each form a loop, the loop of the transmitter coil at least partially overlapping the loop of the receiver coil so as to form a coupling region that is elongate in a first longitudinal direction defining a first axis, the arm extending on a plane that runs perpendicularly to the platform, and the first axis of the coupling region running transversely to the plane.

Abstract: A method comprises performing, by a first coherent radar system on a chip configured to operate in a terahertz range between 0.1 THz and 1 THZ, a first radar scan of a target, the first coherent radar system being in physical contact with a first non-physical scanning device. The first non-physical scanning device then receives first scanning data from the first radar scan, and sends a coordination signal to a second non-physical scanning device. A second coherent radar system on a chip configured to operate in the terahertz range performs a second radar scan of the target, the second coherent radar system being in physical contact with the second non-physical scanning device. The second non-physical device receives second scanning data from the second radar scan, and the first and second scanning data are sent to a processor for a determination as to whether an impermissible object has been detected.

Abstract: Radar for automatic detection and identification concealed objects based on integration of holographic non-scanning antenna array with monopulse high directional accuracy method of fast direction finding and direct digitizing of signals on each directional antenna relatively to processor sampling signals, real time processing of received three-dimensional interferograms in time and frequency domains. Antennas coupled with signal conditioning circuits and SDR (Software Defined Radio) arranged as integrated transceiver antenna modules connected to multi-beam signal processor by digital interface arranged as universal serial bus or microwave and/or fiber optic waveguides or wirelessly. It allows distribution of integrated transceiver antennas modules around vehicle perimeter or between drone's swarm and provides additional system protection against jamming, spoofing or EM pulse. Transformation and processing of different polarizations signals in time domain, frequency domain and multi-axis space domain decreasing false errors probability and enhance identification by spectrum signature.

Abstract: According to one embodiment, a security inspection system includes a determination device and a control device. The determination device performs first determination regarding whether a target has a predetermined object. The control device controls a passage management device which performs second determination regarding whether the target has been permitted to pass. The control device transmits a second signal to the determination device when receiving a first signal from the passage management device. The first signal indicates a start of the second determination. The determination device starts the first determination when receiving the second signal.
