Methods and systems for vehicle radar coordination and interference reduction
A method is provided that includes a vehicle receiving data from an external computing device indicative of at least one other vehicle in an environment of the vehicle. The vehicle may include a sensor configured to detect the environment of the vehicle. The at least one other vehicle may include at least one sensor. The method also includes determining a likelihood of interference between the at least one sensor of the at least one other vehicle the sensor of the vehicle. The method also includes initiating an adjustment of the sensor to reduce the likelihood of interference between the sensor of the vehicle and the at least one sensor of the at least one other vehicle responsive to the determination.
RADAR-BASED DETECTION USING SPARSE ARRAY PROCESSING
Exemplary aspects are directed to a radar-based detection circuit or system with signal reception circuitry to receive reflection signals in response to radar signals transmitted towards objects. The system may include logic/computer circuitry and a multi-input multi-output (MIMO) virtual array to enhance resolution or remove ambiguities otherwise present in processed reflection signals. The MIMO array may include sparse linear arrays, each being associated with a unique antenna-element spacing from among a set of unique co-prime antenna-element spacings.
Transmission Control Method and Related Device
A transmission control method includes steps for obtaining interference information of a first radar on a first frequency band, for example, through listening before transmission. The interference information represents a degree to which the first radar is interfered with on the first frequency band. Transmission duration of the first radar on the first frequency band is determined based on the interference information, where the interference information indicates either a difference between the transmission duration and an initial transmission duration of the first radar, or the transmission duration.
Information Reporting Method, Information Receiving Method, and Apparatus
An information reporting method and apparatus for of automatic or intelligent driving, the method including receiving, by a detection apparatus, a first signal, determining, by the detection apparatus, based on the first signal, an interfered range in a detection range of the detection apparatus, and sending, by the detection apparatus, interference information to a fusion apparatus, where the interference information comprises indication information of the interfered range.
Mover, mover control system, method of detecting object by mover, moving system, and method of controlling mover
Disclosed herein is a mover including an object detecting unit and either a masking processing unit or a transmission restricting unit as an additional processing unit. The object detecting unit detects an object based on a reception signal output from a receiver unit by having a transmitter unit transmit a scanning wave and by having the receiver unit receive a reflected wave, which is a component, reflected from the object, of the scanning wave. The masking processing unit performs masking processing of masking, in accordance with a timing at which, and/or a direction of incidence in which, a disturbance wave, not depending on the scanning wave, is incident on the receiver unit, a portion of the reception signal output from the receiver unit. The transmission restricting unit restricts a transmission range in which the transmitter unit transmits the scanning wave.

Electronic device that uses virtual field to reserve transmission and reception time of radar signal and control method thereof
An electronic device and a control method thereof are provided. The electronic device includes an array antenna and a communication circuit which is electrically connected to the array antenna. The communication circuit is configured to determine a number of specified fields for reserving time for outputting a first signal through the array antenna and receiving a reflection signal corresponding to the first signal reflected by an external object, generate a second signal including information about the number of specified fields, and output the first signal through the array antenna after transmitting the generated second signal to an external electronic device through the array antenna, and receive the reflection signal corresponding to the output first signal.
CROSS-TALK COMPENSATION FOR GRADIOMETER PROBES
A system/device, such as a gradiometer probe for detecting RF signals, or for example for explosive detection, has the shape of the coils in its adjustment mechanism that minimizes the cross-talk between the receiver probe (Rx) and the transmitting antenna (Tx) in such a way as to minimize (or reduce) the areas where the distance between the coils during the adjustment is the smallest. Moving coils along the plain of the coils is one mechanism of achieving it. Having the coils of different shapes, e.g., circular receiver and oval transmitter coils, is another. Many shapes are possible, including circular, oval, elliptical, and polygonal, to give a few examples. In some embodiments both of these methods/approaches are combined in a single device.

A straddle type vehicle comprising a rear fender arranged on an upper side of a rear wheel, and a monitoring device configured to monitor a traveling environment on the periphery of a vehicle, wherein the monitoring device includes a pair of sensors, the rear fender includes a sensor support member configured to support one of the pair of sensors on a left side of a vehicle body and the other on a right side of the vehicle body, the sensor support member includes a pair of left and right side wall portions, and a bottom wall portion configured to connect the pair of left and right side wall portions, and the pair of sensors are arranged along the pair of left and right side wall portions on the bottom wall portion.
Method and Apparatus to Centrally Control and Process Multiple Sensors
A plurality of sensors are controlled and processed by an electronic control unit (ECU). Each sensor compresses the raw data samples, encapsulates them into IP packets, and transmits them to the ECU over the Ethernet transport. The ECU decompresses the IP packets, and individually performs sensor-specific signal processing prior to performing multi-modal sensor fusion. Additionally, if the underlying sensor is a Radar sensor, the ECU performs interference detection, interference mitigation, interference management, transmits compressed beamforming weights to enable transmit beamforming on the Radar sensor.
