Abstract

Système et procédé de détection et de localisation d'au moins un objet, muni de premiers moyens radar émettant des premières ondes électromagnétiques et de premiers moyens de détection de radars. Le système comprend des deuxièmes moyens radar émettant des deuxièmes ondes électromagnétiques et des deuxièmes moyens de détection de radars adapté pour la détection des premières ondes électromagnétiques émises et pour la détermination de premiers paramètres des premières ondes électromagnétiques. Le système comprend aussi des moyens d'estimation du temps de propagation de la première onde électromagnétique entre lesdits deuxièmes moyens radar et lesdits premiers moyens de détection de radars. Enfin le système comprend des moyens de modification de seconds paramètres desdites deuxièmes ondes électromagnétiques adaptés pour que les deuxièmes intervalles temporels à utiliser par l'émission des futures deuxièmes ondes électromagnétiques soient compris dans tout ou partie desdits premiers intervalles temporels compensés dudit temps de propagation.System and method for detecting and locating at least one object, provided with first radar means emitting first electromagnetic waves and with first radar detection means. The system comprises second radar means emitting second electromagnetic waves and second radar detection means suitable for detecting the first emitted electromagnetic waves and for determining first parameters of the first electromagnetic waves. The system also comprises means for estimating the propagation time of the first electromagnetic wave between said second radar means and said first radar detection means. Finally, the system comprises means for modifying second parameters of said second electromagnetic waves adapted so that the second time intervals to be used by the emission of future second electromagnetic waves are included in all or part of said first time intervals compensated for said propagation time.
