Abstract

La présente invention concerne le domaine de la détection passive d'émissions radar. Elle a pour objet un procédé de localisation et/ou de dénombrement passif d'émetteurs radar mis en œuvre par au moins deux plateformes mobiles, chacune desdites plateformes mobiles comprenant au moins un capteur MRE apte à intercepter les lobes d'émission d'émetteurs radar présent dans leur champ de veille et à estimer leurs temps d'arrivée et au moins une plateformes mobiles possédant un capteur MRE comprenant deux récepteurs distants formant une grande base, ledit capteur étant apte à estimer une évolution de phase entre les deux récepteurs de la grande base, la localisation des émetteurs radar étant effectuée en utilisant conjointement des mesures de différence de temps d'arrivée (TDOA) entre les plateformes mobiles et des mesures d'évolution de phase entre les deux récepteurs de la grande base d'au moins une plateforme mobile, ladite localisation étant calculée à partir des lieux des iso-mesures de ces deux méthodes.The present invention relates to the field of passive detection of radar emissions. It relates to a method for locating and / or passive counting of radar transmitters implemented by at least two mobile platforms, each of said mobile platforms comprising at least one MRE sensor capable of intercepting the emission lobes of radar transmitters present in their standby field and to estimate their arrival times and at least one mobile platform having an MRE sensor comprising two remote receivers forming a large base, said sensor being able to estimate a phase change between the two receivers of the large base, the location of the radar transmitters being carried out jointly using arrival time difference (TDOA) measurements between the mobile platforms and phase evolution measurements between the two receivers of the large base of at least one platform mobile, said location being calculated from the locations of iso-measurements of these two methods.
