Efficient Nyström-Based Unitary Single-Tone 2D DOA Estimation for URA Signals

Efficient Nyström-Based Unitary Single-Tone 2D DOA Estimation for URA Signals

We propose an efficient Nyström-based unitary subspace method for low-complexity two-dimensional (2D) direction-of-arrival (DOA) estimation in uniform rectangular array (URA) signal processing systems. The conventional high-resolution DOA estimation methods often suffer from excessive computational...
