Reconfigurable Multi-Beam Steering with Opportunistic Array of UAVs

Simultaneously multi-beam steering techniques are capable for multi-target illuminating, tracking and jamming. The opportunistic array of UAVs proves to be a flexible and less vulnerable platform for these tasks due to the high mobility of its structure. However, most of the existed pattern synthesis and task allocation algorithms developed for opportunistic arrays are heavily time-consumed and thus are not suitable for such a dynamic system of UAVs. Here, a concise and analytical algorithm to determine the probabilities of UAV operating modes and to achieve reconfigurable multi-beam steering is proposed. This algorithm is non-iterative and takes lower computational complexity. With our scheme, task allocation and multi-beam steering are performed with swarm size of up to 2000. According to numerical simulation, the fidelity and efficiency values of the multi-beam steering could reach 0.97 and 0.8, respectively.
