Underdetermined 2D DOA Estimation for Coherent Signals via Sparse Sensor Array With Nested Moving Sampling Scheme

In order to improve the performance of target localization based on multi-sensor system, this paper proposes a novel sparse acoustic vector sensor (AVS) array with nested moving sampling scheme, forunderdetermined two-dimensional (2D) direction of arrival (DOA) estimation of coherent target signals....
