Classification: CPC G | IPC G

Claim 0:
1. An integrated circuit comprising:
a receiver configured to determine a first beat signal based on received and transmitted radar signals;
a processor coupled to the receiver and configured to:
receive the first beat signal;
produce a second beat signal based on the first beat signal, wherein, to produce the second beat signal, the processor is configured 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;
determine a first distance for an 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.
