Abstract
A radar method is described. According to one exemplary embodiment, the method includes generating a first RF oscillator signal in a first chip and supplying the first RF oscillator signal to a transmission (TX) channel of the first chip and transmitting the first RF oscillator signal from the TX channel of the first chip to the second chip via a transmission line.

A method, comprising:
- generating a first radio frequency (RF) oscillator signal in a first chip and supplying the first RF oscillator signal to a transmission (TX) channel of the first chip;
- generating a second RF oscillator signal in a second chip;
- transmitting the first RF oscillator signal from the first chip to the second chip via a transmission line;
- and
- determining a first propagation delay of the first RF oscillator signal arriving at the second chip,
- wherein determining the first propagation delay comprises demodulating the first RF oscillator signal arriving at the second chip using the second RF oscillator signal.
