Claim 12:
13. A method for determining a distance between radar systems, the method comprising:
transmitting, by a transceiver of a first radar system, a first Frequency Modulated Continuous Wave, FMCW, radar signal, which comprises a first sweep profile;
receiving, by the transceiver, a second FMCW radar signal from a second radar system, which comprises a second sweep profile, wherein the sweep profile of the first FMCW radar signal differs from the sweep profile of the second FMCW radar signal;
generating, by a mixer, a beat signal based on the first FMCW radar signal and the second FMCW radar signal;
digitizing, by an analog-to-digital converter (ADC) that is arranged downstream of the mixer, the beat signal;
deskewing, by a deskewing unit, the digitized beat signal by matching the sweep profile of the first FMCW radar signal with the sweep profile of the second FMCW radar signal; and,
determining, by a processing unit, the distance between the radar systems by processing the deskewed beat signal.
