Abstract: A method for processing radar data is described herein. In accordance with one embodiment, the method includes the calculation of a Range Map based on a digital radar signal received from a radar receiver. The Range Map includes spectral values for a plurality of discrete frequency values and a plurality of discrete time values, wherein each spectral value is represented by at least a first parameter. Further, the method includes applying an operation to at least the first parameters in the Range Map for at least one discrete frequency value to smooth or analyze at least a portion of the Range Map.

Abstract: A radar method is described herein. In accordance with one embodiment the method includes receiving a plurality of chirp echoes of transmitted radar signals, generating a digital signal based on the plurality of chirp echoes, and calculating a range map based on the digital signal. The range map includes a plurality of values, each value is represented by an amplitude value and a phase value, and each value is associated with one frequency bin of a set of frequency bins and one chirp echo of the plurality of chirp echoes. The method further includes identifying chirp echoes which are affected by interference and determining, for one or more selected frequency bins, corrected phase values based on phase values that are associated with chirp echoes not identified as affected by interference.

Abstract: A method of operating a pipelined analog-to-digital converter (ADC) having a plurality of output stages includes: performing a first calibration process for the pipelined ADC to update a parameter vector of the pipelined ADC, where components of the parameter vector are used for correcting nonlinearity of the pipelined ADC, where performing the first calibration process includes: providing an input signal to the pipelined ADC; converting, by the pipelined ADC, the input signal into a first digital output; providing a scaled version of the input signal to the pipelined ADC, where the scaled version of the input signal is generated by scaling the input signal by a scale factor; converting, by the pipelined ADC, the scaled version of the input signal into a second digital output; and calibrating the pipelined ADC using the first digital output and the second digital output.
