Interpolation-Based Direction-of-Arrival Estimation for Coprime Arrays via Covariance Matrix Fitting

Interpolation-Based Direction-of-Arrival Estimation for Coprime Arrays via Covariance Matrix Fitting

Coprime arrays can highly increase degree-of-freedom (DOF) by exploiting the equivalent virtual signal. However, since the corresponding virtual array constructed by the coprime array is always a non-uniform linear array (non-ULA), most existing direction-of-arrival (DOA) estimation algorithms fail...
