Abstract: A signal sending method, a signal receiving method, and corresponding apparatuses are provided, and are used for self-driving or assisted driving. In a signal transmission phase, a radar may transmit a signal by using a designed waveform, for example, generate a first frequency modulated continuous wave sequence, and transmit the first frequency modulated continuous wave sequence, where the first frequency modulated continuous wave sequence includes N frequency modulated continuous waves, N is an integer greater than or equal to 1, and a product of a time domain position and a corresponding frequency domain position in a first frequency modulated continuous wave in the N frequency modulated continuous waves meets a first condition.

Abstract: Radar systems, radar-implementation methods, and non-transitory processor-readable mediums storing processor-executable instructions for implementing radar chirp generation and processing are provided. An example set of processor-executable instructions includes instructions for configuring each of a plurality of transmitters to transmit each chirp of a set of chirps with a specific spin frequency that is different for each transmitter, in which the specific spin frequency is a function of an index value identifying the corresponding transmitter, and a number of the plurality of transmitters; and determining, in a frequency domain, a Doppler representation based on reflected signals that are reflected from one or more objects contacted by one or more chirps of the transmitted sets of chirps, in which the Doppler representation includes multiple spectrum bands including one or more empty spectrum bands determined by the specific spin frequency function, wherein none of the object(s) appear(s) in any of the empty spectrum band(s).

Abstract: Resources are configured, by frame/subframe/slot/symbol, for uplink communication components, downlink communication components, radar sensing components, or flexible components. Flexible components are configured by symbol for uplink or downlink communications, radar sensing, or flexible usage. Full, partial or no overlap between resources for uplink, downlink or sidelink communication and resources for radar sensing may be configured. Frequency configuration for radar sensing may be in absolute units or grid units, and waveforms other than OFDM may be used for radar sensing. Configuration may be initiated by a base station in response to explicit or implicit request by a UE for sensing resources. A UE may sense resources within a configured resource pool for availability before using the resources for radar sensing.

Abstract: A frequency modulated continuous wave (FMCW) radar device and a signal processing method thereof are provided. The frequency modulated continuous wave radar device includes a transmitter stage circuit, a frequency synthesizer, a receiver stage circuit, a pre-stage circuit, and a signal processing circuit. The transmitter stage circuit transmits a transmitting signal. The frequency synthesizer generates the transmitting signal associated with a chirp period. The receiver stage circuit receives a receiving signal including a periodic interference signal with a noise period associated with the chirp period. The pre-stage circuit outputs a to-be-processed signal including multiple frames according to the receiving signal and the transmitting signal. The signal processing circuit groups the frames into multiple frame groups. The signal processing circuit generates a processed signal by sampling at least one frame from the multiple frames in each of the frame groups with an identical sampling rule.

Abstract: An anomaly detection device includes a processor and a non-transitory memory that stores a program. The processor executes the program to operate an anomaly detection device as an obtainer that obtains a first object detection result generated by a first object detection device that is included in a first apparatus which is a vehicle and detects an object in the vicinity of the first apparatus and a second object detection result generated by a second object detection device that is included in a second apparatus in the vicinity of the first apparatus and detects an object in the vicinity of the second apparatus; a determiner that determines whether at least one of the first apparatus or the second apparatus is being attacked, by comparing the first object detection result and the second object detection result; and an outputter that outputs a result of determination by the determiner.

Abstract: A method for evaluating radar signals in a radar system including multiple sensor units, which are each capable of detecting objects in the surroundings of the radar system, the detection areas of the sensor units at least overlapping one another. In the method, each sensor unit calculates a short message from the radar signals received by it, whose data volume is smaller than the complete detection result, but which at least contains data which allow for the identification of potential objects and for the determination of a probability that the potential object is a real object, and at least one evaluation instance receives the entirety of all short messages of all sensor units and, on the basis of these short messages and selected detection results of the sensor units, calculates a consolidated detection result.

Abstract: A method related to processing interference between cooperative radars, where a radar obtains configuration information used to indicate a ratio of a quantity of first data update periods to a quantity of second data update periods in a sending period. The first data update period is used to send a first radio signal, and the second data update period is used to send a second radio signal. Waveform configurations of the first radio signal and the second radio signal are different, to effectively reduce mutual interference between the first radio signal and the second radio signal.
