<p>The system has a transmitter assembly (1) for emitting a signal (4) on two transmission frequencies (F1, F2), where the transmission frequencies are separated by a selected emission frequency gap. An analysis unit analyzes the signal received by a receiver assembly (2) to measure the frequency difference between the transmission and reception frequencies of the signal to calculate the radial velocity of a moving system (10) according to a function of deviation between the receiving frequency and the emission frequency gap.</p> |
