Abstract :
This study deals with the bearing and the range estimation for buried objects problem. We propose a new method that combines the array processing approaches with an accurate acoustical modeling for the buried objects localization problem in the underwater acoustics environment. This method incorporates the exact solution for the scattered field (instead of using the plane wave model) in the MUSIC method, uses the focusing operator to decorrelate the signals and estimates both the range and the bearing objects. Finally, the performances of the proposed method are validated on experimental data recorded during an underwater acoustics experiments.
