Target detection method for ground penetrating radar and associated radar

摘要

A method of detecting at least one target buried in an area of the ground, using ground penetrating radar, the method comprising the steps of: Acquiring (201) a measurement of a signal emitted by each antenna transmission and reflected in the ground zone, Determining (202) an estimate, in the frequency domain, of the propagation channel for each pair consisting of a transmission antenna and a reception antenna, defining a first hypothesis H0 corresponding to an absence of target in the ground area, defining a second hypothesis H1 corresponding to the presence of at least one target in the ground area, carrying out (203) a test of the likelihood ratio between the likelihood of the matrix of channel under the second hypothesis H1 and the likelihood of the channel matrix under the first hypothesis H0, to conclude that a target is present at a given position in the zone d on the ground.
