Abstract
Determining a speed and a range of an object by generating at least a first, second, and third interval-specific tone phase signals associated with at least three successive time intervals, wherein at least two of the generated and transmitted tones are different frequencies; determining at least a first, second and third interval-specific average phase value from the respective interval-specific tone phase signals; and then determining a range estimate of the object and determining a speed estimate of the object using at least two phase differences between the at least first, second and third interval-specific average phase values.
