摘要：
A method for locating at least one target, in an electromagnetically absorbent environment, includes: emitting at least one electromagnetic excitation signal from a source； receiving, by an acoustic sensor, an acoustic signal from emission of the excitation signal； detecting, in the received acoustic signal, a first time of receipt of a first response to the excitation signal from an acoustic disturbance caused by electromagnetic heterogeneity of the target in the environment； estimating a first distance between the target and the acoustic sensor using the first time of receipt； detecting, in the same received acoustic signal, a second time of receipt of a second response to the excitation signal from an acoustic disturbance caused by acoustic heterogeneity of the target in the environment； estimating a second distance between the source and target using the second time of receipt； obtaining a location of the target from the first and second estimated distances.
