Abstract
Large-scale unmanned aerial vehicle (UAV) formations are vulnerable to disintegration under electromagnetic interference and fire attacks. To address this issue, this work proposed a distributed formation method of UAVs based on the 3 × 3 magic square and the chain rules of visual reference. Enlightened by the biomimetic idea of the plane formation of starling flocks, this method adopts the technical means of airborne vision and a cooperative target. The topological structure of the formation’s visual reference network showed high static stability under the measurement of the network connectivity index. In addition, the dynamic self-healing ability of this network was analyzed. Finally, a simulation of a battlefield using matlab showed that, when the loss of UAVs reaches 85% for formations with different scales, the UAVs breaking formation account for 5.1–6% of the total in the corresponding scale, and those keeping formation account for 54.4–65.7% of the total undestroyed fleets. The formation method designed in this paper can maintain the maximum number of UAVs in formation on the battlefield.
Highlights
In August 2018, the U.S Department of Defense released the Unmanned Systems Integrated Roadmap 2017–2042, which reemphasized that the development of autonomous technology is of great importance for improving the efficiency and performance of unmanned systems as well as soldiers [1]
In order to integrate the advantages of the Vicsek model (VM) and its improved models into a largescale unmanned aerial vehicle (UAV) formation method, this paper summarized the advantages in each model and proposed the 3 × 3 magic square formation method that is capable of anti-jamming and anti-deception visually
Formation Methods and Simulation Based on the work above, this chapter elaborates the distributed formation method based on the 3 × 3 magic square and the chain rules of visual reference
Summary
In order to integrate the advantages of the VM and its improved models into a largescale UAV formation method, this paper summarized the advantages in each model and proposed the 3 × 3 magic square formation method that is capable of anti-jamming and anti-deception visually This biomimetic formation method is enlightened by the plane formation of starling flocks and is based on the chain rules for visual reference. It adopts the technical means of airborne vision and cooperative targets and possesses strong antielectromagnetic interference and anti-deception capabilities.
