SYSTEM AND METHOD FOR THE THREE DIMENSIONAL LOCATING OF AN OBJECT IN A VOLUME

摘要

The invention relates to a system (11) for locating an object (4) in a volume (3) comprising: - a first matrix of scanning antennas (1) positioned in a first plane; - first detection means (4) arranged so as to detect a first signal received by the object in response to a first electromagnetic signal emitted by the first matrix towards the volume; - first means of two-dimensional locating (6) that are arranged so as to determine the position of a projection of the object into the first plane as a function of the first signal received; in which the system comprises: - a second matrix of scanning antennas (2) which is positioned in a second plane, the second plane not being parallel to the first plane; second detection means (4) arranged so as to detect a second signal received by the object in the volume in response to a second electromagnetic signal emitted by the second matrix of antennas towards the volume; - second means of two-dimensional locating (5) which are arranged so as to determine the position of a projection of the object in the second plane as a function of the second signal received; - means of three-dimensional locating (7) arranged to locate the object in a reference frame formed by the first plane and the second plane, as a function of the position of the object in the first plane and in the second plane.
