ABSTRACT:
Method and apparatus for pulse spacing measurement with periodic pulse pairs, in particular in pulse radar, by measuring the time interval between the instants of the coincidence of a pulse edge with a trigger level which is set in a predetermined ratio to the peak value of the pulse, characterized in that the pulse pairs are sampled by the sampling method with the aid of sampling pulses whose recurrence period is smaller by a predetermined small time difference than the recurrence period of the pulse pairs, that for each time-transformed pulse obtained by the sampling the peak value is determined and a trigger level having a predetermined ratio to the peak value is set, and that the time interval between the instants of the coincidence of the trailing pulse edge of each time-transformed pulse and the associated trigger level is measured.
