Visibility Domain Direction-of-Arrival Optimization for Arbitrary 2-D Arrays
A visibility-modelling based method is introduced to determine the elevation and azimuth angles for a signal received at a quasi-randomly arranged (2-D) array. The method is optimal for the number of antennas when the array is configured such that no antenna baselines are repeated. Simulation shows...

| description | A visibility-modelling based method is introduced to determine the elevation and azimuth angles for a signal received at a quasi-randomly arranged (2-D) array. The method is optimal for the number of antennas when the array is configured such that no antenna baselines are repeated. Simulation shows that our method has comparable accuracy to subspace-based acrlong doa algorithms like acrfull music and measured data shows that it is both more accurate and faster than visibility based methods like acrlong ra all-sky imaging. |
