Abstract: A vehicle, radar system for the vehicle and method of operating the vehicle is disclosed. The radar system includes a transmitter, a receiver and a processor. The transmitter transmits a source signal into a region proximate the vehicle. The receiver receives a reflected signal formed by reflection of the source signal from an object in the region. The processor obtains non-linear terms of a phase from the reflected signal and resolves a Doppler ambiguity of the object using the non-linear terms. A navigation system navigates the vehicle with respect to the object based on the resolved Doppler ambiguity.
