A radar system comprising: a plurality of antennas configured to detect a reflected radar signal reflected by an object in a field-of-view of the system, wherein each antenna of the plurality of antennas is configured to output a detected signal indicative of the reflected radar signal detected by each of the antenna; and a controller configured to: receive the detected signals from the plurality of antennas, determine if a target is present in the field-of-view based on the detected signals, determine a frequency profile of each detected signal, wherein each of the frequency profiles includes a plurality of amplitude values and phase values associated with frequency bins that correspond to an amplitude sample and phase sample of a particular frequency profile at a particular frequency, where said frequency bins correspond to a range of a potential target, and the amplitude of the frequency profiles is an indication of the amount of radar signal reflected at a particular range; determine a phase difference of each frequency profile at two distinct frequencies wherein the frequency profile is characterized by values stored in an array of frequency bins, and the phase difference is determined based on a difference between a first phase value associated with a first frequency bin of the array, and a second phase value associated with a second frequency bin of the array; and determine a phase variation based on changes in the phase difference versus a relative position of each antenna, and indicate that the target includes more than one object if the phase variation is greater than a variation threshold. a plurality of antennas configured to detect a reflected radar signal reflected by an object in a field-of-view of the system, wherein each antenna of the plurality of antennas is configured to output a detected signal indicative of the reflected radar signal detected by each of the antenna; and a controller configured to: receive the detected signals from the plurality of antennas, determine if a target is present in the field-of-view based on the detected signals, determine a frequency profile of each detected signal, wherein each of the frequency profiles includes a plurality of amplitude values and phase values associated with frequency bins that correspond to an amplitude sample and phase sample of a particular frequency profile at a particular frequency, where said frequency bins correspond to a range of a potential target, and the amplitude of the frequency profiles is an indication of the amount of radar signal reflected at a particular range; determine a phase difference of each frequency profile at two distinct frequencies wherein the frequency profile is characterized by values stored in an array of frequency bins, and the phase difference is determined based on a difference between a first phase value associated with a first frequency bin of the array, and a second phase value associated with a second frequency bin of the array; and determine a phase variation based on changes in the phase difference versus a relative position of each antenna, and indicate that the target includes more than one object if the phase variation is greater than a variation threshold. receive the detected signals from the plurality of antennas, determine if a target is present in the field-of-view based on the detected signals, determine a frequency profile of each detected signal, wherein each of the frequency profiles includes a plurality of amplitude values and phase values associated with frequency bins that correspond to an amplitude sample and phase sample of a particular frequency profile at a particular frequency, where said frequency bins correspond to a range of a potential target, and the amplitude of the frequency profiles is an indication of the amount of radar signal reflected at a particular range; determine a phase difference of each frequency profile at two distinct frequencies wherein the frequency profile is characterized by values stored in an array of frequency bins, and the phase difference is determined based on a difference between a first phase value associated with a first frequency bin of the array, and a second phase value associated with a second frequency bin of the array; and determine a phase variation based on changes in the phase difference versus a relative position of each antenna, and indicate that the target includes more than one object if the phase variation is greater than a variation threshold.
