The invention relates to a mapping method that implements a radar operated in a passive mode. Such a radar can be used for locating an object capable of reflecting an electromagnetic wave generated by a transmitter having a known position. The method comprises using mobile objects (3) capable of reflecting the radiations received from opportunity transmitters (2). The method comprises the following steps: determining, in a distance Doppler matrix of the radar (1), points related to the deviations between the radiations directly received from the transmitters (2) and the radiations reflected by the mobile object (3); reporting on a map to be developed a probable area for locating the singularities of the electromagnetic field generated or reflected by the ground; overlaying a plurality of probable areas during the movement of the mobile object (3) in order to obtain the location of the singularities.

L'invention concerne un procédé de cartographie mettant en oeuvre un radar utilisé en mode passif. On peut utiliser un tel radar pour localiser un objet susceptible de réfléchir une onde électromagnétique émise par un émetteur dont on connaît la position. On utilise des objets mobiles (3) susceptibles de réfléchir des rayonnements reçus d'émetteurs d'opportunité (2). Le procédé comporte les opérations suivantes : déterminer dans une matrice doppler distance du radar (1 ), des points relatifs aux écarts entre les rayonnements reçus directement des émetteurs (2) et les rayonnements réfléchis par l'objet mobile (3), reporter sur une carte à établir une zone probable de localisation de singularités du champ électromagnétique émis ou réfléchi par le sol, croiser plusieurs zones probables lors du déplacement de l'objet mobile (3) pour obtenir la localisation des singularités.
