Abstract: A radar device may generate an integrated range-velocity map by combining data from a plurality of range-velocity maps. Each range-velocity map may be associated with a respective radar channel from a plurality of radar channels. The radar device may identify a first peak in the integrated range-velocity map. The first peak may indicate one or more radar targets in the integrated range-velocity map and being identified by a first bin having a first range-velocity bin index. The radar device may determine a first data set by extracting, from each range-velocity map, data that is included in a respective bin associated with the first range-velocity bin index. The radar device may process the first data set to determine a first set of phase imbalances associated with the plurality of radar channels.

Abstract: A method for determining a nonlinearity characteristic of a receiver path includes generating a set of N×M digital samples by repeating N times selecting an scaling factor from a set of N scaling factors, generating a version of a test signal, the version of the test signal corresponding to a test signal scaled by the respective scaling factor, processing the respective version of the test signal in at least a part of the receiver path to generate a respective processed signal, and storing M digital samples corresponding to the respective processed signal. Fourier-transformed data are generated using at least a portion of the set of N×M digital samples and a nonlinearity characteristic of the receiver path is determined based on the Fourier-transformed data.
