Abstract
An automotive radar system and method are configured to transmit and receive radar signals. A first received radar signal is processed to generate a range-Doppler data frame. A first target cluster is identified at a first range in the range-Doppler data frame. A range spectrum data set associated with the first range is extracted from the range-Doppler data frame. A low-pass filter is applied to the range spectrum data set to extract a first portion of a spectrum of the range spectrum data set and an inverse fast Fourier transform (IFFT) of the first portion of the spectrum is performed to generate a time-domain set of signal magnitudes. A super-resolution spectral estimation is applied to the time-domain set of signal magnitudes to identify a first range of a first target associated with the first target cluster. The first range is transmitted to a vehicle controller.
