The present invention relates to a solution to problems linked with the TOA mode (Time Of Arrival) or TDOA mode (Time Difference Of Arrival) passive location of targets. The TOA or TODA mode passive location of a target involves a meshing (division) into volumes of the space in which the location target is situated. The set of volumes defining this mesh is analysed in an iterative manner. At each iteration, each volume of interest is divided into sub-volumes of identical dimensions. According to the invention, a volume of interest is a volume including at least one point belonging to the searched location area whose shape has to be determined. The iterative process stops when the dimensions of the sub-volumes obtained a the current iteration corresponds to the desired resolution. The invention can particularly be used in 2D or 3D location systems including means for implementing TOA, TDOA or mixed modes.

La présente invention concerne la résolution des problèmes liés à localisation passive de cibles en modes TOA (Time Of Arrival) ou TDOA (Time Différence Of Arrival). Le procédé de localisation passive d'une cible en mode TOA ou TDOA mettant en oeuvre un maillage (découpage) en pavés de l'espace dans lequel se situe la zone de localisation. L'ensemble des pavés formant ce maillage est analysé de manière itérative. A chaque itération chaque pavé d'intérêt est découpé en sous-pavés identiques de taille inférieure. Un pavé d'intérêt est, selon l'invention, un pavé comportant au moins un point appartenant à la zone de localisation recherchée dont on veut déterminer la forme. Le processus itératif s'arrête lorsque la taille des sous-pavés obtenus à l'itération en cours correspond à la résolution souhaitée. L'invention s'applique en particulier aux systèmes de localisation 2D ou 3D, comportant des moyens pour mettre en AEuvre des modes TOA, TDOA, ou des modes mixtes.
