Abstract
A method for determining a range of a target includes receiving a first time based radar return signal, converting the first time based radar return signal into a first frequency domain signal, detecting a peak of the first frequency domain signal, the peak corresponding to a coarse target range, receiving a second time based radar return signal, using the detected peak of the first frequency domain signal and the second time based radar return signal, converting the second time based radar return signal into a second frequency domain signal, and detecting a peak of the second frequency domain signal, the peak corresponding to a fine target range.
