title = "Investigating DOA Performance of a Rotated Synthetic Array in the Presence of Speed Error",
abstract = "This paper explores a novel emitter localization concept where a linear antenna array is conformed along the rotating blades of drones. As the blades rotate, the linear array synthesizes a two-dimensional radial array structure, enabling direction-ofarrival (DOA) estimation. A key challenge in this scenario is the presence of angular speed mismatch during rotation, which leads to phase misalignment and geometric distortion of the synthetic aperture. This work analytically derives the Cramer-Rao Lower Bound (CRLB) to quantify how angular speed errors affect DOA performance. Numerical simulations further validate the analysis, showing that angular speed errors could significantly degrade estimation accuracy, especially at moderate-to-high signal-tonoise ratios and in the undersampled regions. These findings underscore the need for precise rotational control or correction mechanisms in blade-mounted antenna systems.",
