    Abstract: L'invention concerne les déclencheurs altimétriques utilisés notamment pour le déclenchement de dispositifs de freinage de bombe ou pour l'ouverture de bombes ou roquettes cargo. Elle a pour but d'obtenir un déclenchement correct en cas d'un largage à basse altitude aussi bien avec que sans palier ressource. Elle consiste à prévoir pour un déclencheur altimétrique une phase d'activation au cours de laquelle il se voit imposer un niveau de consigne de déclenchement évoluant progressivement d'une valeur quasi nulle au niveau nominal de déclenchement. On distingue sur la figure le schéma d'un déclencheur altimétrique avec sa sonde altimétrique (1) qui délivre une tension électrique proportionnelle au niveau mesuré, une source de tension de seuil (2) délivrant une tension électrique proportionnelle au niveau nominal de déclenchement, un circuit d'application progressive de la tension de seuil (3) et un comparateur (4) comparant la tension de mesure avec la tension de seuil lui parvenant par le circuit (3) d'application progressive de tension.

    Abstract: The invention relates to a remote identification device. An interrogator (1) sends a UHF interrogation wave (3) to a responder (2), the interrogation wave (3) being modulated. The responder (2), at each period of the signal for modulating the interrogation wave (3) accumulates the energy transported by the latter, the energy received being converted into voltage for supplying means for coding (37) and transmitting (38) a UHF response wave (4) to the interrogator (1). Application: identification of objects via a radar signal.

    Abstract: The distance between the target and the measurement means is segmented into adjacent distance compartments, the first one of which starts at the zero distance. Each distance compartment has an associated energy level obtained by the demodulation of the delay measurement signal resulting from the product of correlation between the emitted signal and the received signal reflected by the target. The disclosed method consists in creating two distinct aliasings of the spectrum of the signal measurement signal, the energy level of which corresponds to the first distance compartment, these aliasings being achieved on the part of the spectrum corresponding to negative distances. This two distinct aliasings make it possible to obtain two distinct energy levels on the totality of the first distance compartment, and thus enable the measurement of all the distances on this first distance compartment, including the very small distances, even almost zero distances, by comparisons and analyses of the two energy levels. Application: to the measurement of short distances for the detection of short-distance targets.
