A method for determining a localization parameter of an object includes generating a plurality of estimates of a first frequency-domain amplitude of a baseband signal from the object, each estimate corresponding one of a plurality of temporal segments of the baseband signal. The method also includes determining the first frequency-domain amplitude as most common value of the plurality of estimates, and determining the localization parameter therefrom. A localization system includes a memory and a microprocessor. The memory stores instructions and is configured to store a baseband signal having a temporal frequency component and a corresponding first frequency-domain amplitude. The microprocessor is adapted to execute the instructions to: (i) generate a plurality of estimates of the first frequency-domain amplitude each corresponding to a respective one of a plurality of temporal segments of the baseband signal, and (ii) determine the first frequency-domain amplitude as the most common value of the estimates.
