    摘要: An apparatus comprises a dielectric material having a first surface and a second surface with a varying thickness between the first surface and the second surface. The first surface has a substantially hyperbolic curved shape with a single vertex, and the second surface has a substantially planar shape. The combination of the substantially hyperbolic curved shape and the dielectric material is chosen to compensate for different delays in electromagnetic waves impinging the first surface and traveling through the dielectric material such that the electromagnetic waves exiting the dielectric material through the second surface after traversing the dielectric material have a phase profile either constant or varying smoothly from the center to the edge.

    摘要: A method comprises scanning a subject with a coherent radar beam from a single chip operating in the terahertz range, and executing instructions, on a processor, to create one or more digital images based said scanning. One or more digital images are combined at the processor to form a super image, and based on the super image, the processor determines whether the subject is carrying a concealed object. if the subject is determined to be carrying a concealed object, and certain alert-generating rules are met, an alert is generated.

    摘要: An apparatus includes a lens with substantially flat first surface and a substantially tiered second surface opposite the substantially flat first surface, where the substantially tiered second surface has at least a central tier and a second tier, the central tier and the second tier each having a different thickness from the other tier, and where the thickness of each tier as measured orthogonally from the substantially flat first surface is chosen to provide a delay for the signal passing through the lens to approximate the characteristics of a Luneburg type lens as a radar beam is swept across the substantially first surface.

    摘要: An apparatus comprises a first and second coherent radar system on a first chip configured to operate in a terahertz range to provide a frequency modulated continuous wave, and having a first and second field of view, respectively. The apparatus further comprises a first processor in communication with the first coherent radar system and configured to include instructions to send a first signal to the first coherent radar system to scan a target with the first field of view, and a second processor in communication with the second coherent radar system and configured to collaborate with the first processor, and further configured to include instructions to send a second signal to the second coherent radar system to scan a target within the second field of view.
