<p>The invention relates to a mapping method implementing a radar used in passive mode. It is possible to use such a radar for locating an object likely to reflect an electromagnetic wave transmitted by a transmitter the position of which is known. Movable objects (3) capable of reflecting rays received from transmitters of opportunity (2) are used. The method comprises the following operations: determining, in a distance Doppler matrix of the radar (1), points relative to the deviations between the rays received directly from the transmitters (2) and the rays reflected by the movable object (3), transferring to a map to be established a probable zone of location of singularities of the electromagnetic field transmitted or reflected by the ground, crossing several probable zones during the movement of the movable object (3) in order to obtain the location of the singularities.</p> |
