Abstract
The object of the invention is to provide a method and a circuit by means of which the signals generated in a stationary base station (1) and a flying station e.g. missile (3) can be regulated to a common frequency. The frequency of the signals generated in the base station (1) is adjusted to the frequency of the signals generated by the flying station. To perform the method the base station (1) uses a circuit (2) having a frequency generator (5) whose control input is connected to a first mixer (6) via a series circuit consisting of a converter (8) and a filter (14). The signal input of this mixer (6) is connected to two receivers (9, 10) which receive at least two different frequencies (fP) (fRP) in order to determine a control signal for the frequency generator (5). The flying station (3) has a frequency generator (40) whose output is connected to at least one mixer (41). The second input of mixer (41) is connected to the reception antenna (43) via a receiver (42). The output of the mixer (41) is connected to the transmission antenna (45) via a filter (44). <IMAGE>
