System and Method for a Radio Frequency System

摘要

In accordance with an embodiment, a method includes producing a baseband variable frequency signal and producing a substantially fixed frequency signal by phase-locking an oscillator to a substantially fixed reference frequency. The method further includes upconverting the baseband variable frequency signal by mixing the variable frequency signal with the substantially fixed frequency signal to produce an RF variable frequency signal.

1. A method of operating a radio frequency (RF) system comprising:
producing a baseband variable frequency signal; producing a substantially fixed frequency signal, wherein producing the substantially fixed frequency signal comprises phase-locking an oscillator to a substantially fixed reference frequency; upconverting the baseband variable frequency signal, wherein upconverting comprises mixing the variable frequency signal with the substantially fixed frequency signal to produce an RF variable frequency signal; transmitting the RF variable frequency signal toward a target; and determining at least one of a distance and velocity of the target based on receiving a reflected RF variable frequency signal.
