摘要： A system and method to generate a family of orthogonal signals for a code division multiple access (CDMA) radar system involve selecting a first signal of the family of orthogonal signals for transmission by one of a plurality of transmitters of the radar system. The method includes using an algorithm to determine a second signal of the family of orthogonal signals. The algorithm uses cross-correlation values between candidate signals for consideration as the second signal of the family of orthogonal signals and the first signal. The method also includes transmitting the first signal of the family of orthogonal signals and the second signal of the family of orthogonal signals simultaneously from two different transmitters, and obtaining and processing reflections resulting from transmission of the first signal of the family of orthogonal signals and the second signal of the family of orthogonal signals.

摘要： A method of mitigating vibration in a radar system on a moving platform includes obtaining received signals resulting from reflections of transmitted signals by one or more objects in a field of view of the radar system. The received signals are a three-dimensional data cube. The method also includes processing the received signals to obtain a first three-dimensional map and second three-dimensional map, estimating the vibration based on performing a first detection using the second three-dimensional map, and cancelling the vibration from the first three-dimensional map to obtain a corrected first three-dimensional map. A corrected second three-dimensional map is obtained by further processing the corrected first three-dimensional map; and a second detection is performed using the corrected second three-dimensional map.

摘要： An example method for performing a joint radon transform association includes detecting, by a processing device, a target object to track relative to a vehicle. The method further includes performing, by the processing device, the joint radon transform association on the target object to generate association candidates. The method further includes tracking, by the processing device, the target object relative to the vehicle using the association candidates. The method further includes controlling, by the processing device, the vehicle based at least in part on tracking the target object.

摘要： A system and method to perform target detection includes transmitting frequency modulated continuous wave (FMCW) pulses as chirps from a radar system. The method also includes receiving reflections resulting from the chirps, and processing the reflections to obtain a range-chirp map for each beam associated with the transmitting. Curve detection is performed on the range-chirp map for each beam, and one or more targets is detected based on the curve detection.

摘要： A vehicle, radar system for a vehicle, and method of determining a radial velocity of an object via the radar system. The radar system includes a transmitter, receiver and processor. The transmitter transmits a source signal towards an object, and the receiver for receives a reflection of the source signal from the object. The processor obtains a Doppler measurement related to a radial velocity of the object, wherein the Doppler measurement includes a Doppler ambiguity, obtains a range walk rate for the radial velocity of the object, and resolves the Doppler ambiguity of the Doppler measurement using the range walk rate to obtain the radial velocity of the object.

摘要： A radar system includes one or more antennas to emit transmit signals and receive reflected signals resulting from reflection of the transmit signals by an object. The transmit signals are linear frequency modulated continuous wave (LFMCW) signals. The radar system also includes a transmission generator to generate the transmit signals. The transmission generator includes a controller to control output of a first of the transmit signals and a second of the transmit signals in succession. A time between transmission of the first of the transmit signals and the second of the transmit signals is less than a duration of a stabilization period of a first oscillator used to generate the first of the transmit signals.

摘要： A method includes performing object detection by a radar sensor system. The object detection includes generating and transmitting object-detection (OD) chirps on an OD channel of a plurality of radar channels employed by the radar sensor system. The method further includes monitoring unused radar channels for interference and determining that at least one of the unused radar channels is free of interference. The method still further includes performing object detection by generating and transmitting one or more OD chirps on the determined interference-free channel.

摘要： A system and method for time-frequency coding for interference mitigation of sensors is presented that includes generating and transmitting, from a vehicle, a first chirp signal by a first sensor, in a first time-channel and in a first frequency-channel. The method may also include generating and transmitting, a second chirp signal by a second sensor, in a second time-channel and in the first frequency-channel and the receiving, by the first sensor, a first reflection signal from objects from the first chirp signal. In addition, there may be a receiving, by the second sensor, a second reflection signal from objects from the second chirp signal. In addition, the first time-channel is orthogonal to the second time-channel, and the transmitting of the second chirp signal is offset in time from the transmitting of the first chirp signal by an amount less than a duration of the first chirp signal.
