- W3048355188 abstract "Optimal rotation of an unmanned aerial vehicle (UAV) mounted with a cross array for enhanced two-dimensional (2D) direction estimation is discussed, and a novel method based on Cramer–Rao bound (CRB) minimisation is proposed. CRB serves as the lower bound for direction-of-arrival (DOA) estimation, which directly determines the localisation performance of jamming sources. Based on the fact that CRB differs while UAV's rotation angle changes, a theoretical closed-form solution for an optimal rotation in the 2D direction estimation is derived, and then the authors can acquire capability enhancement of DOA estimation after the optimal rotation. Rigorous analysis and multiple simulations demonstrate the feasibility and effectiveness of the proposed scheme." @default.
