摘要： The invention relates to a sensor system (200, 300, 400) for a motor vehicle, comprising a sensor housing and an active or passive sensor (102) arranged therein and held on a movable sensor holder (201, 401), having a sensor technology based on radiation detection and a measurement apparatus assigned to the sensor (102) and a control apparatus, coupled to said measurement apparatus, for the sensor holder (201, 401), wherein the sensor housing has a cover (106, 301) that is signal-transmissive for the sensor (102) on its side located in the detection direction of the sensor (102), and wherein the detection range (108, 109) of the sensor (102) in the region of the signal-transmissive cover (106, 301) has a lower extent than the signal-transmissive cover (106, 301), wherein the sensor system (200, 300, 400) is characterized in that the measurement apparatus is designed such that it is suitable for checking, in the detection range of the sensor (102), whether and in which section the signal-transmissive cover (106, 301) has a region with reduced signal transmissivity (202), wherein the measurement apparatus interacts with the control apparatus in such a way that the control apparatus is able to change the position of the sensor (102) in such a way that the region with reduced signal transmissivity (202) lies outside the detection range (108, 109) of the sensor (102). The invention furthermore relates to a method for operating such a sensor system (200, 300, 400) and to a motor vehicle that is equipped with such a sensor system (200, 300, 400).

摘要： A radar-enabled device that manages radar interference. In particular, the radar-enabled device detects a radar signal transmitted by a second radar-enabled device, transmits a notification of the detected radar signal, receives localization information associated with the second radar-enabled device, and sets a device location based on the received localization information. Additionally, the radar-enabled device may adjust a timing of radar signal transmissions to avoid subsequent detections of radar signals transmitted by the second radar-enabled device.

摘要： Some demonstrative aspects include radar apparatuses, devices, systems and methods. In one example, a radar system may include a plurality of radar devices. For example, a radar device may include one or more Transmit (Tx) antennas to transmit radar Tx signals, one or more Receive (Rx) antennas to receive radar Rx signals, and a processor to generate radar information based on the radar Rx signals. In one example, the radar system may be implemented as part of a vehicle. In other aspects, the radar system may include any other additional or alternative elements and/or may be implemented as part of any other device or system.

摘要： Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network entity for wireless communications can receive a sensing reference signal reflected from a target. The network entity can detect and measure remote interference (RI) based on the sensing reference signal.

摘要： The invention relates to a computer-implemented method for identifying a radar transmitter from a set of corresponding received pulses, each pulse being associated with a respective time of arrival. The method includes determining an observed signature of the radar transmitter based on a distribution of the time gaps between consecutive times of arrival. For each transmitter class among a plurality of predetermined transmitter classes, each transmitter class being associated with at least one expected signature, the method includes calculating a proximity score between the observed signature and each expected signature associated with said transmitter class. Each expected signature is a function of an expected distribution of the time gaps between consecutive times of transmission for said transmitter class, and for a predetermined pulse loss rate. The method also includes assigning the radar transmitter to the transmitter class associated with the expected signature that provides the best proximity score.

摘要： An apparatus comprising one processor and one memory including computer program code to: generate at least one sample corresponding to at least one radar/non-radar signal; form at least one spectrogram using time and frequency domain characteristics of the sample; wherein the spectrogram is formed via subdividing an observation window of the sample into time slots of a given duration, computing a power spectral density for a subset of the time slots having a higher determined energy relative to other time slots, and combining one or more computed power spectral densities of the subset; pass the spectrogram to a model to detect a presence of the radar signal and classify the radar signal as either interference/noise or radar present, and estimate a bandwidth of the detected radar signal; and determine the radar signal to be in-band or out-of-band relative to a shared spectrum hand, based on the estimated bandwidth.

摘要： Provided is a radar signal processing method based on Orthogonal Frequency Division Multiplexing (OFDM). The method includes transmitting an OFDM transmission signal to at least one target, receiving an analog reception signal reflected from the at least one target, converting the analog reception signal into a digital reception signal, obtaining a first velocity of the at least one target based on the digital reception signal, and processing the digital reception signal based on the first velocity to obtain a recovery signal having reduced inter-channel interference.
