Abstract
A radar system and method of extending a parameter of a location of a target obtained by radar is disclosed. The system receives an echo signal that is a reflection of a radar source signal from the target. The echo signal is sampled and a peak for the echo signal is objected in frequency space. For a peak that is located at a frequency greater than a Nyquist frequency of the echo signal, the peak is moved to a negative domain of the frequency space and the location of the target is determined using the peak in the negative domain.
