Abstract: The review of parametric methods of multiple underwater sources direction of arrival (DOA) estimation by a passive array of sensors is presented in this paper. The most common in literature model of far, narrow-band sources is assumed. Deterministic and stochastic maximum likelihood methods and their advantages and disadvantages are described. The subspace fitting approach is presented as well. A good performance of parametric methods is payed with high computational cost of searching the optimal parameters set. The reparameterisation method, lowering the computational cost of optimisation, is described in the last section of this paper.
