The method involves calculating the difference (RTD=R12-0, R12-1) between a first time reference of a first oscillator and a second time reference of a second oscillator at two successive instants (t0,t4). This is determined as a function of the propagation time difference associated with the first and second oscillators. The variation between the calculated reference time differences is determined by a time unit. The frequency difference between the oscillators is determined in response to a variation in the calculated time differences which is greater than a given threshold. |
