Résumé:
We present a new imaging technique dedicated to the
detection of a target embedded in a strongly scattering
medium. Our technique separates the single-scattered
echoes from the multiple scattering background. Once
this operation is performed, the detection of the target
is achieved by applying the DORT method. The quality
of detection is assessed theoretically with Random Matrix
Theory and shown to be better than what is obtained with
echography and the classical DORT method.
