The Maximum Localization Error Bound of Distributed Array for Focused Energy Delivery in Precision Electronic Warfare
2020
Focused energy delivery is the core technology for bringing energy to a specific area by the ultra-sparse array. This paper mainly focuses on one of its typical applications: precision electronic warfare (PREW), and analyzes the influence of localization errors caused by each nodes on focused energy delivery. According to the model proposed, we obtain the analytical expressions of the objective function appropriately and introduce the localization errors. Under the reasonable assumption based on the theory of algebra and geometry, the maximum localization error bound is concluded that it should be less than 1/8 of the carrier wavelength. Finally, numerical results demonstrate the correctness of the maximum localization error bound derived, and indicate the impact of different errors on the model.
