Narrowband direction-of-arrival estimation of near-field sources using compressed sensing

This contribution deals with the direction-of-arrival estimation of narrowband signals in near-field scenarios using compressed sensing strategies. The considerations relate to a single snapshot of the signal impinging on a sensor array. For the estimation a near-field formulation of the array manifold vector is used. This approach also allows to draw conclusion on the distance between the array and the sources. Simulation as well as measurement results are provided to present the performance of the proposed method.
