  • Publication number: 20240069186
    Abstract: A radar transceiver includes a phase shifter that is controlled to apply an induced phase shift in a first subset of chirp signals of a frame of chirp signals, which also includes a second subset of chirp signals in which no phase shift is applied. Other circuitry generates digital signals based on received reflected signals, which are based on transmitted signals. Processing circuitry performs a Fast Fourier Transform (FFT) on a first subset of digital signals, corresponding to the first subset of chirp signals, to generate a first range-Doppler array, and performs a FFT on the second subset of digital signals, corresponding to the second subset of chirp signals, to generate a second range-Doppler array; identifies peaks in the first and second range-Doppler arrays to detect an object; and compares a phases of peaks at corresponding positions in the first and second range-Doppler arrays to determine a measured phase shift between the two peaks.

  • Patent number: 11899095
    Abstract: Systems and methods are provided for Doppler processing for frequency-modulated continuous wave (FMCW) radar systems. Range-gate data representing the position of an object within a region of interest is generated at a radar sensor. A first Doppler Fast Fourier Transform (Doppler-FFT) is performed on the range-gate data to provide a first set of Doppler-FFT data. A velocity associated with a signal amplitude that exceeds a noise floor is identified in the first set of Doppler-FFT data. A correction value for the range-gate data is determined from the identified velocity. The range-gate data is modified using the determined correction value to provide modified range-gate data. A second Doppler-FFT is performed on the modified range-gate data to provide a second set of Doppler-FFT data.

  • Publication number: 20240031214
    Abstract: A non-transitory device-readable medium, which may be embodied in a device, such as a radar receiver, stores instructions that, when executed by processing circuitry, are configured to perform operations to identify a region of interference. An analog signal is generated based on received signals reflected from a target object and an interfering object. The analog signal is converted to an initial time-domain data set. Processing circuitry is configured or instructed to perform a transform operation on the initial time-domain data set to generate a frequency-domain data set, based on which a region of interference may be identified. Subsequent operations may be performed to facilitate identification of the region of interest including thresholding, inverse transforming, subtracting, and/or combining. The processing circuitry may be further configured or instructed to generate repaired time-domain data from which corrupted time-domain samples to remove data associated with the interfering object.
