Title
(EN) A DEVICE FOR LOCALISING A TRANSMITTER UNIT
(FR) DISPOSITIF PERMETTANT DE LOCALISER UNE UNITE EMETTRICE
Abstract
(EN)
A device for localising a transmitter unit (2) comprises a base unit (1) and at least one such transmitter unit (2). The transmitter unit comprises means (4), which enable attachment of the transmitter unit to an object (3), and a transmitter member, which is arranged to transmit a signal having a determined frequency. The base unit (1) comprises a receiver member which is arranged to receive said signal. Furthermore, the base unit (1) comprises a number of antennas (7), which are positioned on a relatively small distance (a) from each other and each arranged to send said signal, and a processing member which is arranged to calculate at least the direction to said transmitter unit (2) by means of the signal sent by the antennas (7).

Cette invention concerne un dispositif permettant de localiser une unité émettrice (2), lequel comprend une unité de base (1) et au moins une de ces unités émettrices (2). L'unité émettrice comprend un système (4) qui permet de la fixer à un objet (3), ainsi qu'un élément émetteur qui va émettre un signal à une fréquence prédéterminée. L'unité de base (1) comprend un élément récepteur qui va recevoir le signal. L'unité de base (1) comprend en outre un certain nombre d'antennes (7) qui sont disposées à une distance (a) relativement réduite les unes des autres et qui vont chacune détecter le signal, ainsi qu'un élément de traitement qui va calculer la direction au moins de l'unité émettrice (2) à l'aide du signal détecté par les antennes (7).
