N2 - Joint direction-of-arrival (DOA) and range estimation based on frequency diverse array (FDA) have been a critical issue in radar detection, tracking, and navigation. This paper first proposes a bidirectional extension frequency diverse coprime array (BE-FDCA) to obtain an extended 2D virtual array with a larger degree of freedom (DOF). Furthermore, on top of BE-FDCA, we introduce a sparse reconstruction algorithm, referred to as SR-BE-FDCA, to avoid time-consuming peak searches. The algorithm includes two key steps: sparse reconstruction of Decoupled Atomic Norm Minimization (DANM) and 2D ESPRIT estimation. With the aid of these designs, our approach achieves more accurate DOA and range estimations. Finally, numerical simulations are implemented to demonstrate the effectiveness of our method.
