—A new algorithm for improving 2D-Direction of Arrival Estimation (2D-DOAE) accuracy and estimator performance has been carried out. Subspace concept has been employed into ESPRIT method to reduce the computational complexity and the model’s non-linearity effect into 2D-DOAE problem. The algorithm accuracy is verified by closed-form Cramér–Rao bound (CRB). The simulation results show that the proposed algorithm realizes estimation process better than those of the previous estimation techniques leading to the estimator performance enhancement.
