摘要： Various aspects of the disclosure relate to millimeter wave ranging with six degrees of freedom. For example, a multi-gigabyte link (e.g., an IEEE 802.11ad link or an 802.11ay link) and RF/Antenna diversity modules can be used to conduct round trip time (RTT) distance measurements between an anchor point and a station. Relative location information (e.g., degrees of freedom) between the wireless devices can then be determined based on the distance measurements.

摘要： Systems (100) and methods for determining a location of a tag (310). The methods involve: receiving, at each detector of a plurality of detectors (202-216, 306, 308), a device transmission periodically transmitted from the tag; determining, by the detectors, Received Signal Strength Indictors (“RSSIs”) for the device transmission received thereat; determining, by a computing device (218), a probable location of the tag within the passage, first demarcated area or second demarcated area using the RSSIs and relationships between the RSSIs; determining a first likelihood value indicating the likelihood that the probable location is correct; and determining an estimated location of the tag within the passage, first demarcated area or second demarcated area based on the probable location when the first likelihood value meets a first criteria.

摘要： A system (1) and a method for finding the direction (θ) of a target (6) in a detection plane, e.g. the azimuthal plane. The system comprises a plurality of transceivers (2a, 2b, 2c) which transmit continuous-wave radio signals (4) oriented in distinct main directions of transmission (5a, 5b, 5c) and receive a return radio signal (7) reflected from a target (6), wherein the transceivers have partially overlapping angular fields of view. A controller (9) analyzes the transmitted and return signals by calculating signal amplitudes associated with the return signals and determining the direction (θ) of the target as a direction of a mean signal vector obtained from signal vectors having as a modulus the signal amplitudes of respective transceivers.

摘要： A radar system includes transmitters and receivers configured for installation and use in a vehicle. The transmitters transmit radio signals. The receivers receive radio signals that include the transmitted radio signals reflected from objects in an environment. Each receiver has a controller, a buffer, and a post-buffer processor. The receiver processes the received radio signals and stored data samples in the buffer. The buffer operates in a plurality of modes defined by the controller. Two or more modes of operation of the plurality of modes are performed with a same set of data samples stored in the buffer. The post-buffer processor receives data samples from the buffer and performs at least one of correlation processing to determine object ranges, Doppler processing to determine object velocity, and, in combination with other receivers of the plurality of receivers, further processing to determine angular locations of the objects.

摘要： A method of a ranging and positioning with sensor STA/neighbor AP is proposed. An initiating wireless device establishes an FTM procedure with a responding wireless device in an indoor wireless local area network. The initiating device exchanges FTM frames with the responding device and thereby receiving a first set of timestamps from the responding device. The initiating device receives a second set of timestamps associated with the exchanged FTM frames from one or more listening devices. Finally, the initiating device determines location information from the first and the second set of timestamps.

摘要： A radar enclosure that includes two side wall components, a top aerodynamically streamlined shape component, the two side wall components extending from the base surface to the a top aerodynamically streamlined shape component forming an enclosure cavity, and an antenna supporting component disposed in the enclosure cavity and configured to support a phased array antenna, the phased array antenna being disposed at an angle with respect to a normal to the base surface is disclosed. The networking of the radar with such enclosures increases the radar coverage by adding to the possible collection of locations and thus potentially increasing the data to be analyzed—ultimately increasing the accuracy of the readings.

摘要： The present invention relates to a parking support Apparatus and Method of operation comprising of an mm-wave radar sensor, having an integrated mm-wave IC front end. The proposed Apparatus is capable of detecting the parking obstacle object distance and angle, having inherently low cost system topology, suitable as a replacement in functionality for the commonly used ultrasound sensors. The proposed apparatus topology consist of one transmitting and two planar antennae, mm-wave radar topology with one down conversion chain and one transmitter chain based on FMCW radar, CW radar and Doppler radar, analog combining circuitry and N mm-wave power detectors, where N takes integer values from 1 and larger. The specific proposed method of operation is adjusted to a dedicated application. A combination of more than one proposed apparatus enables smart observation of the parking area in front of the moving platform with wired or wireless connection to the information evaluation and control entity. The proposed apparatus topology with lower complexity consist of one transmit and two planar antennae, mm-wave radar topology without any down conversion chain and one transmitter chain based on CW radar operation, analog combining circuitry and N mm-wave power detectors, where N takes values from 1 to 3. The system operation topology allows full distance and obstacle angle calculation by the apparatus itself in one topology solution or to have the information being calculated, combining more sensors, using low complexity apparatus topologies, also proposed in this innovation. The integration of the proposed apparatus in the vehicle bumper is inherently possible and may be optically and functionally provided as an efficient replacement for ultrasound parking assist systems. The complete proposed sensor apparatus topologies with integrated antennae, mm-wave IC and digital processing parts may be realized in a module smaller than 1×1×0.5 cm and operating in the 77-81 GHz band.
