Abstract: Performing a Fast Fourier Transformation (FFT) with increased resolution by applying an adaptive left shift to signed binary integers of an input of a radix kernel and adaptive right shift to signed binary integers of an output of a butterfly of the radix kernel which is based on a leading bit count of the input. The adaptive left shift increases a resolution of the radix kernel computation and the adaptive right shift determines a number of bits of the increased resolution preserved in an output of the radix kernel.

Abstract: Aspects of the present disclosure relate to a radar system and method of operation thereof, whereby a spectrogram is generated by processing circuitry of a radar system by converting samples, of reflections of transmitted radar signals reflected by an object in an environment of the radar system, into a time-frequency domain, determining at least one threshold based on at least one MIN-of-MAX value for magnitudes of a frequency signal of the spectrogram, generating an interference-suppressed spectrogram by removing or attenuating interference components from the spectrogram based on the at least one threshold, and generating interference-suppressed samples based on the interference-suppressed spectrogram.
