  • Abstract
    The performance of frequency estimation procedures for sinusoidal signals in the presence of phase perturbations plays an important role in continuous-wave radar systems for distance measurement, as it directly determines the ranging accuracy. For the most widely used frequency estimator, the fast Fourier transformation, the influence of deterministic deviations of the transmit signal from the ideal curve in FMCW/FSCW radars is investigated, quantified and verified with measured radar data.
