Abstract: This target indicator makes it possible to increase the accuracy and efficiency of guidance of homing missiles towards a target. For indicating ground targets, it comprises an ovoid casing (15) equipped with a rip cord (4), with a magnet (1) and with a coil (11) for detecting a variation in flux at the time of an impact on a magnetic surface. Arranged inside the casing are a battery (6), an electronic control and transmission circuit (5) and a barrel (2) of pulse generators (13) connected to one another by means of pyrotechnic delay devices (12). The barrel opens out onto a single nozzle (3) inclined relative to the axis (Z) of the casing. After impact on the ground, the electronic circuit (5) commands the ignition of the first pulse generator. The other pulse generators cause jumps until fastened on a magnetic surface by means of the magnet (1). After the detection of the flux variation, electronic circuit (5) commands the ignition of the rip cord (4) for the purpose of ejecting the casing (15) and the barrel of pulse generators (13) and triggers an ultrahigh frequency or infrared transmitter, depending on the particular homing missile to be homed in.

Abstract: 12 MARQUEUR D'OBJECTIF POUR ATTIRER DES PROJECTILES MUNIS D'UN AUTODIRECTEUR Ce marqueur permet d'accroître la précision et l'efficacite du guidage d'autodirecteurs vers un objectif. Pour marquer des objectifs terrestres, il comporte: une enveloppe ovoïde (15) dotée: d'un cordeau de rupture (4), d'un aimant (1), et d'une bobine (11) de détection de variation de flux lors d'un impact sur une surface magnétique. A l'intérieur de l'enveloppe sont disposés : une pile (6), un circuit électronique (5) de commande et d'émission, et un barillet (2) d'impulseurs (13) reliés entre eux par des retardateurs pyrotechniques (12). Le barillet débouche sur une tuyère unique (3) inclinée par rapport à l'axe (Z) de l'enveloppe. Après impact sur le sol, le circuit électronique (5) commande la mise à feu du premier impulseur. Les autres impulseurs provoquent des sauts jusqu'à fixation sur une surface magnétique, par l'aimant (1). Après détection de la variation de flux, le circuit électronique (5) commande la mise à feu du cordeau de rupture (4), pour éjecter l'enveloppe (15) et le barillet d'impulseurs (13); et declenche un émetteur hyperfréquence, ou infrarouge, selon l'autodirecteur à rallier. Figure 1.

Abstract: The invention concerns an accurate synchronising device for synchronising signals transmitted from a transmitter (1) to receivers (2), comprising at least, at transmitter level, means for generating a synchronising signal with a recurrence interval substantially equal to the minimum travel time resolution between the transmitter and a receiver, and at receiver level, controllable means for delaying (31) the synchronising signal and a synchronising loop comprising downstream delaying means (31) and a semi-reflecting blade (32), and comprising correlating means (34, 35, 37, 38, 39, 42, 43) and means automatically controlling (40) the delaying means (31) a function of the correlation, a signal received by a receiver being synchronised when the correlation function of two successive recurrences (36) of the synchronising signal passing through the semi-reflecting blade (32) is at its maximum. The invention is applicable to accurate, even ultra-accurate, synchronisation of data distributed from a transmitter to receivers remote from each other, for example for using complex electromagnetic and/or optical systems.
