Abstract :
In this paper a MUSIC algorithm for locating buried cylindrical shells using the scattering field at a wideband frequency is developed. The algorithm presented here modifies the conventional direction finding array precessing techniques, it uses the spatial complexities of the fields combined to the focusing operator to decorrelate the signals that allows us to estimate both the range and the bearing of the objects in the region of interest. Finally, the performances of the proposed method are validated on simulated data and experimental data recorded during an underwater acoustics experiments
