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.

Abstract: A method is provided. In some examples, the method includes performing, by processing circuitry, a first transform operation on a first time-domain data set to generate a frequency-domain data set. In addition, the method includes determining, by the processing circuitry, that at least one portion of the frequency-domain data set satisfies a first threshold magnitude. The method also includes performing, by the processing circuitry, an inverse transform operation on the at least one portion of the frequency-domain data set to generate a second time-domain data set. The method further includes identifying, by the processing circuitry and based on the second time-domain data set, a region of interference in the first time-domain data set.

Abstract: A frequency-modulated continuous wave (FMCW) radar system is presented. The FMCW radar system includes a receiver configured to receive a radar reflection signal. The radar system further includes an interference detection module, which is configured to identify a portion of the radar reflection signal corresponding to the time period during which the radar reflection signal exceeds a threshold. The FMCW radar system further includes a hysteresis module configured to adjust the identified portion of the radar reflection signal based on the portion of the signal and a hysteresis configuration. The FMCW radar system further includes a mitigation module configured to mitigate interference based on the output of the hysteresis module.
