Abstract
A radar system configured to compensate for a carrier characteristic offset includes a transmitter that transmits a code signal based on a transmitter carrier characteristic and a receiver that receives an echo of the code signal based on a receiver carrier characteristic. Additionally, the radar system includes a control unit that identifies a tracking path between the transmitter and the receiver that is at least partially independent from the path of the code signal and the echo of the code signal. Using an index of the tracking path, the code unit estimates a carrier characteristic offset between the transmitter and the receiver and then compensates for this estimated carrier characteristic offset.
Claims18
A radar system, comprising:
- a transmitter having a transmitter carrier frequency, the transmitter configured to transmit a code signal;
- a receiver having a receiver carrier frequency, the receiver configured to receive an echo of the code signal;
- and
- a control unit configured to:
- identify a tracking path between the transmitter and the receiver;
- estimate an offset between the transmitter carrier frequency and the receiver carrier frequency based on an index of the identified tracking path;
- and
- compensate for the offset based on the estimation,
- wherein the tracking path comprises a communication path that is at least partially independent of the code signal and the echo of the code signal.
A method of operating a radar system, the method comprising:
- transmitting a code signal by a transmitter having a transmitter carrier frequency;
- receiving an echo of the code signal by a receiver having a receiver carrier frequency;
- identifying a tracking path between the transmitter and the receiver;
- estimating an offset between the transmitter carrier frequency and the receiver carrier frequency based on an index of the identified tracking path;
- and
- compensating the offset based on the estimation,
- wherein the tracking path comprises a communication path that is at least partially independent of the code signal and the echo of the code signal.
