Abstract
A radar system and method of determining a tracking parameter for a target in a radar system is disclosed. A transmitter transmits a source signal at a target and a receiver receives an echo signal from the target corresponding to the source signal. A processor provides a discrete frequency spectrum for the echo signal, shifts the discrete frequency spectrum in frequency space by a selected amount to obtain a shifted spectrum, filters the shifted spectrum using a filter that is shifted in frequency space a same amount as the shifted spectrum, and determines a tracking parameter of the target from a central frequency of the frequency space at which an intensity of the shifted and filtered spectrum is a peak intensity.
