Direction-of-Arrival Estimation With ULA: A Spatial Annihilating Filter Reconstruction Perspective
Direction-of-arrival (DOA) estimation under low signal-to-noise ratio (SNR) and snapshot deficient scenarios has practical application value.Since the array output of the uniform linear array (ULA) can be viewed as a linear NEUROMED KIDS combination of the equal interval sampling complex exponentials, it can be annihilated by a spatial annihilating
