摘要：

In this paper, a new method for simultaneous range and bearing estimation for buried objects in the presence of an unknown colored noise is proposed. We propose a method based on MUSIC (MUltiple SIgnal Classification) which evaluates the time delay of arrival (TDOA) of the reflection of an emitted signal on objects. This is achieved by exploiting the wideband of the signal and the assumption that the emitted signal spectrum is known. The bearing and the range objects are expressed as a function of those TDOA. The proposed algorithm is compared with a classical coherent signal subspace method on experimental data recorded during underwater acoustic experiments.
