Abstract

Le système radiotechnique permet une mesure sans ambiguïté des coordonnées spatiales d'objets radio, y compris d'objets mobiles, qui émettent des signaux radioélectriques. Le système radiotechnique comprend un système terrestre d'émission de signaux radioélectriques multi-point avec N ≥ 5 points d'émission de signaux radioélectriques, qui sont numérotés dans l'ordre, et dont les coordonnées de centres de phase des antennes sont connues de l'objet radio. Les points d'émission sont aptes à l'émission synchronisée et ordonnée des signaux radioélectriques par séries. Chaque objet radio comprend les dispositifs suivants en liaison fonctionnelle : un dispositif de réception de signaux électriques à capacité de réception et d'identification des signaux radioélectriques conformément au point d'émission correspondant, et un dispositif d'enregistrement de moments de temps de leur réception dans un système de temps de référence réglé dans l'objet radio, et un système d'informations apte à la mesure des coordonnées du centre de phase d'une antenne objet radio sur la base desdites coordonnées et desdits moments de temps de réception des signaux radioélectriques de la série à l'aide des équations proposées. Le système d'informations est apte à mesurer d'autres caractéristiques de trajectoire de l'objet à émission radioélectrique sur la base des coordonnées de l'objet radio mesuré en série, inter alia, à l'aide de méthodes statistiques de mesures de trajectoires. Le système radiotechnique ne nécessite pas de synchronisation générale de l'ensemble des objets radio à émission et réception de signaux radioélectriques.
