Fast Direction-of-arrival Estimation of Multiple Targets Using Deep Learning and Sparse Arrays

In this work, we focus on improving the Direction-of-Arrival (DoA) estimation of multiple targets/sources from a small number of snapshots. Estimation via the sample covariance matrix is known to perform poorly, since the true manifold structure is not revealed for a small number of samples. First,…
