The present electronic generator of modulated subcarrier pulse signals includes a module (15) for modulating a pulse train, the position and amplitude of which are controllable, forming a switching signal (S3); a switching module (16), connected to the output of the module (15) for modulating a pulse train, including at least one transistor (22), controlled by said switching signal (S3), a voltage-controlled frequency-locking oscillator (18) having a frequency-locking band around a free oscillation frequency controlled by a control voltage, connected to the output of the switching module (16), the switching module making possible the injection of a periodic pulse signal (S4) having a frequency spectrum including at least one frequency line within said frequency locking band. Such arrangement makes it possible to obtain, at the output of the oscillator, frequency-controlled, phase-controlled and amplitude-controlled modulated subcarrier pulsed signals (S5).
