The method of triggering for controlling the activating of the charge of the projectile before the collision of the latter with the target is characterised in that there is transmitted, towards the front of the projectile 10, brief periodic light pulses by means of a light-emitting diode, a synchronous detection of the reflected pulses is carried out and the electrical signal representing each received pulse is compared, after attenuation, with the delayed signal representing the preceding pulse. <IMAGE>
