<p>This method for locating at least one target in an electromagnetically absorbent environment comprises the following steps: emitting (100) at least one electromagnetic excitation signal from a source; receiving (102), by an acoustic sensor, an acoustic signal resulting from the emission of this excitation signal; detecting (106), in the received acoustic signal, a first time of receipt of a first response to the excitation signal, said first response resulting from an acoustic disturbance caused by an electromagnetic heterogeneity of the target in the environment; estimating (110) a first distance between the target and the acoustic sensor using this first time of receipt; detecting (108), in the same received acoustic signal, a second time of receipt of a second response to the excitation signal, said second response resulting from an acoustic disturbance caused by an acoustic heterogeneity of the target in the environment; estimating (112, 114) a second distance between the source and the target using this second time of receipt; obtaining (116) a location of the target from the first and second estimated distances.</p> |
