Claim 12:
13. A non-transitory computer-readable storage device storing instructions that, when executed by at least one processor core, cause the at least one processor core to:
receive a first beat signal corresponding to a reflected radar signal associated with an object;
produce a second beat signal based on the first beat signal, in which the instructions, when executed by the at least one processor core, cause the at least one processor core to perform a Fourier transform on the first beat signal to produce a frequency domain representation of the first beat signal, determine a first frequency associated with the frequency domain representation of the first beat signal, and demodulate the first beat signal based on the first frequency to produce a first intermediate signal;
determine a first distance for the object based on a second frequency associated with the second beat signal;
determine a first phase based on the first distance;
determine a second phase based on at least one of the first beat signal or the second beat signal; and
determine a second distance for the object based on the second phase.
