Abstract	Subspace based methods for direction-of-arrival (DoA) estimation, generally works on the assumption that the source is located at the far-field region, so signal wave front impinging on an array is plane. When this condition is broken, performance of these algorithms becomes degraded and the algorithms are unable to focus the source located at the near-field. Measuring the path traveled by the signal from the source to each array element, the signal phase at each array element can be correctly computed so we can construct the true steering vector associated to the signal emitted from a near-field source having assumed the distortion of the spherical wave front. We conducted some simulations and measurements to analyse this approach.
