Abstract: It is described a radar system (100), comprising:

i) a transmitter (110) having a transmitter carrier characteristic, configured to transmit a code signal (S);
ii) a receiver (120) having a receiver carrier characteristic, configured to receive an echo (E) of the code signal (S); and
iii) a control unit (130) configured to:
a) identify a carrier characteristic tracking path (T) between the transmitter (110) and the receiver (120),
b) estimate an offset between the transmitter carrier characteristic and the receiver carrier characteristic based on the identified tracking path (T), and
c) compensate for the offset, in particular establish coherency, based on the estimation.
iv) The tracking path (T) comprises hereby a communication path that is at least partially independent of the code signal (S) and the echo (E) of the code signal (S).
