    Abstract: An antenna apparatus and a method of operating the antenna apparatus can include a group of receive antenna elements and a transmit antenna array comprising transmit antenna elements, wherein the transmit antenna array is located centrally in a phased array aperture that includes the transmit array antenna and the plurality of receive antenna elements. An isolation area can isolate the transmit antenna array from the receive antenna elements in the phased array aperture, and the phased array aperture can operate with a hybrid dual mode comprising a radar mode and an active beaming steering mode. The radar mode can be a multiple input multiple output (MIMO) radar mode, and the beamforming mode can be an antenna beamforming mode.

    Abstract: A method for activating a vehicle function, by an activation device, from a user's “hands-free” access equipment. Activation of the function triggered by detection of a press of the user on a contact surface of the vehicle. The device includes at least one transceiver located under the contact surface able to communicate with the piece of equipment via ultra-wideband. The method includes: transmission of waves to the piece of equipment; reception of reflected waves; comparison, during a predetermined length of time of: i) values of the phase of the reflected waves with a predetermined phase-value profile exhibiting a phase rotation, and ii) values of the amplitude of the reflected waves with a predetermined amplitude-value profile exhibiting an increase in amplitude; detection of a press of the user on the contact surface depending on the result of the comparisons; activation of the vehicle function if the press has been detected.

    Abstract: A method for estimating the distance of an element with respect to a vehicle on the basis of a detection module. The method includes, implemented by the detection module, determining the standard deviation of the phase of signals reflected from the element for each distance index of a series of distance indices, determining, in the order of the series, the first index for which the standard deviation is below a predetermined threshold for at least a predetermined length of time, and estimating the distance of the element with respect to the detection module on the basis of the determined index, the estimated distance corresponding to the predetermined distance associated with the determined index.

    Abstract: Apparatus, systems, and methods are provided for localization of a region within a patient's body using markers implanted within the region. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region; one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region; a light source for delivering light pulses into the region whereupon the markers modulate reflected signals. A processor of the probe processes the modulated reflected signals at one or more of the surface locations to determine marker locations within the region to obtain a reference frame, determine distance values corresponding to distances from the respective markers to the distal end at each of the surface locations, and determine coordinates of the surface locations relative to the reference frame to generate a three dimensional model of the body region.

    Abstract: A two-dimensional phased subarray MIMO radar apparatus includes a transmission array and a reception array. The transmission array is configured to emit transmission signals, which are orthogonal to each other, towards a target object and extends in a first direction. Moreover, the transmission array includes a plurality of transmission phased subarrays. The reception array is configured to receive reflected signals, which are reflected from the target object, among the emitted transmission signals and extends in a second direction intersecting the first direction. Moreover, the reception array includes a plurality of reception phased subarrays. Each of the plurality of transmission phased subarrays includes a plurality of transmission antennas. Each of the plurality of reception phased subarrays includes a plurality of reception antennas. A first transmission phased subarray and a second transmission phased subarray are adjacent transmission phased subarrays among the plurality of transmission phased subarrays. A spacing from an end of the first transmission phased subarray in the first direction to an end of the second transmission phased subarray in the first direction is a first spacing. The first spacing is greater than or equal to an aperture of each of the plurality of transmission phased subarrays.

    Abstract: System and methods for implementing a vector sensor array surface wave radar is provided. In one or more examples, the system can include a vector sensor array antenna that includes electromagnetic elements collectively configured to receive surface wave reflections generated by radar transmit antenna waves reflecting back from targets of interest. Once received by the vector sensor array, in one or more examples, the system can further include components that can process the incoming signal and use the incoming single to determine the location of one or more targets. In one or more examples, the vector surface array antenna can include three separate loop antennas that are arranged orthogonally to one another, and three dipole antennas that are arranged orthogonally to one another. In one or more examples, the vector surface array antenna can be configured to receive signals in the high frequency (HF) band.

    Abstract: An ultra-wideband (UWB) ranging method comprises determining, by a first device, that the first device is within proximity of a second device. Responsive to the determination, the first device negotiates a value to use as a UWB session key for securing UWB communications with the second device. The negotiation occurs via a communication protocol different from a UWB communication protocol. The first device controls a UWB subsystem therein to encrypt information communicated via the UWB subsystem based on the negotiated value of the UWB session key instead of a default value for the UWB session key that is specified in the UWB communication protocol. The information facilitates determining the distance between the first device and the second device.
