摘要： A multi node radar network system is disclosed. The system includes a base node configured to transmit a directional 5G RF signal, a request node configured to request the base node to transmit the 5G RF signal, and one or more listening nodes configured to receive reflections of the 5G RF signal off of a target object. The system further includes a computation module configured to determine the location of the target object from data received from at least one of the base node, the request node, or the one or more listening nodes. A method for determining the position of a target object in a multi node radar system is disclosed.

摘要： A system for accurate geospatial location and time transfer using radio transmissions without satellite signals. A position and timing measurement system uses standard uncorrelated radio broadcast signals, each of which transmits on an assigned frequency from a known position defined in latitude and longitude, and each of which transmits a modulated or unmodulated carrier signal. A reference unit at known fixed position receives the said standard broadcast signals in the vicinity, samples the frequencies and content values of their signals and broadcasts the said measured frequency and content data nearly simultaneously with a time mark representing the time of said measurement and further broadcasts its position in latitude and longitude. A mobile unit at an unknown position to be determined receives the said standard broadcast signals in the vicinity and measures the time of arrival of their broadcast, recording the time of said measurement.

摘要： Systems and methods for determining precise pick-up locations for passengers who have requested autonomous vehicle rides. In particular, systems and methods are provided for using wireless signals to determine user location. In some examples, wireless ranging technology, such as Ultra Wide Band (UWB), is used to determine the user location. Wireless transceivers are used to determine a mobile device's range, and range information from multiple transceivers is used to determine the mobile's device's position. In some examples, triangulation is used to determine user location, such as triangulation between one or more wireless transceivers and the mobile device. In various examples, wireless transceivers are installed on autonomous vehicles, and in some examples, wireless transceivers are installed in various static locations (e.g., on buildings, lamp posts, or other structures.

摘要： The invention relates to a method (for determining calibration data for an airborne goniometry apparatus comprising an antenna array of several antennas, from several sets of calibration data measured in-flight by said goniometry apparatus, each associated with a measured angular position and comprising an amplitude datum and a phase datum measured by each antenna in said antenna array at said measured position.
The method comprises, for an estimated angular position, a phase (200) of calculating an estimated calibration data set and comprising the following steps: for each measured position, normalizing (204) the data set measured at said measured position, with respect to the phase data measured by each antenna, said normalizing providing as many normalized data sets as there are antennas for each measured position; for each antenna, calculating (206) a candidate data set by interpolating the measured data sets at said measured positions and previously normalized with respect to the phase measured by said antenna; selecting (210), as the estimated calibration data set, the candidate data set whose phase reference has the highest energy among said candidate data sets. It also concerns a computer program and an apparatus implementing such a method, a calibration table obtained by such a method and a goniometry apparatus calibrated with such a method.

摘要： A method for locating an object in a facility includes determining position with respect to time of a material handling device associated with a movable vehicle within the facility Signal strength of a signal emitted by at least one identification tag affixed to the object is measured with respect to time. A time that the object is deposited at a fixed position by the material handling device is determined from the measured signal strength. The location in the facility of the fixed position is established using the determined time and the determined position with respect to time.

摘要： This disclosure describes, in part, techniques for generating location information associated with a video. For instance, an electronic device may use a radar sensor to generate radar data. The electronic device may then analyze the radar data in order to determine a location associated with an object. In some instances, the location may correspond to at least a first coordinate along a first axis and a second coordinate along a second axis. The electronic device may also generate image data using the imaging device. Additionally, the electronic device may analyze the image data in order to determine that the image data represents an object and/or a type of object. The electronic device may then generate location data representing an identifier for the object and the location. Next, the electronic device may send the image data and the location data to one or more computing devices.

摘要： A grouping unit separates, into groups, reflection points included in plural sets of reflection-point information items based on positional parameters of the respective reflection points in a first direction. Each of the positional parameters of a corresponding one of the reflection points in the first direction represents a position of the corresponding one of the reflection points in the first direction. A measuring unit performs a two-dimensional trilateration localization for each of the groups based on at least one reflection point included in a corresponding one of the groups to thereby calculate a location of the at least one reflection point included in each of the groups in a second plane. The second plane is defined by the second direction and a group center direction of the corresponding one of the groups.
