Abstract
A method for detecting at least one target buried in an area of the ground, using a ground-penetrating radar, the method includes the steps of: acquiring a measurement of a signal transmitted by each transmitting antenna and reflected in the area of the ground, converting an estimate, into the frequency domain, of the propagation channel for each pair consisting of a transmitting antenna and of a receiving antenna, defining a first hypothesis H0 corresponding to an absence of target in the area of the ground, defining a second hypothesis H1 corresponding to the presence of at least one target in the area of the ground, performing a test of the likelihood ratio between the likelihood of the channel matrix under the second hypothesis H1 and the likelihood of the channel matrix under the first hypothesis H0, in order to conclude whether a target is present at a given position in the area of the ground.
