Abstract: A system comprises a personal device such as one used by law enforcement, and a housing containing a portable radar system with both a ranging resolution and lateral resolution sufficient to detect an object concealed on a person (e.g., one that operates in the THz range), where the housing is configured to be mounted in contact with the personal device such that when mounted, the combined handheld device and housing have a form factor that allows it to retain its characteristic as a personal device, and where the portable radar system is configured to, when in operation, emit a radar beam and to receive a reflection of the emitted radar beam.

Abstract: A system comprises a conducted energy weapon configured to emit at least one conductive probe in substantially an aimed direction, along with a housing containing a portable radar system with both a ranging resolution and lateral resolution sufficient to detect an object concealed on a person. The housing can be rigidly mounted on or in the conducted energy weapon, and the portable radar system can, when in operation, emit a radar beam and to receive a reflection of the emitted radar beam.

Abstract: A system for scanning targets for concealed objects comprises a set of analog imaging components of a portable radar system with both a ranging resolution and lateral resolution sufficient to detect an object concealed on a person, where the analog imaging components are contained with a first housing and in communication with digital processing components contained in a second housing, where the digital processing components are configured to receive imaging information from the analog components for processing. Each housing is configured to be attached to a user's article of equipment.

Abstract: 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.

Abstract: An apparatus comprises a coherent radar system on a single chip configured to transmit high-frequency signals with a center frequency in a submillimeter wavelength range that corresponds to a frequency range of 0.3 THz and no greater than 0.4 THz. The radar system on the single chip (RSOC) comprises a phased array transmitter antenna configured to emit a radar beam with a center frequency of greater than 0.3 THz and no greater than 0.4 THz. The RSOC further includes a receiver configured to provide a voltage signal to a wide band receiver voltage controlled oscillator to form a phased array receiver antenna configured to receive reflected signals from the emitted radar beam.

Abstract: An apparatus comprises a coherent radar system on a single chip that operates in a range of operation in a terahertz range, where the range of operation is between approximately 0.1 THz and 1 THz.

Abstract: 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.
