    Abstract: A radar system may include a radar sensor circuit, a compression estimation circuit, a compression circuit, and a data storage circuit. The radar sensor circuit may receive a set of sensor data associated with a radar chirp signal. The radar sensor circuit may generate a set of range data associated with the set of sensor data, which may include first range data for a first range bin and second range data for a second range bin. The compression estimation circuit may determine a first compression ratio for the first range data and a second compression ratio for the second range data. The compression circuit may compress the first and second range data based on the first and second compression ratios respectively. The compressed first and second range data may be stored at the data storage circuit.

    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 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.

    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.
