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. |
