摘　　要：地面激光系统由于障碍物遮蔽和光束传输发散,实际毁伤效果不够理想。利用无人机平台,可以对目标进行抵近照射。但是普通无人机负载能力小,无法悬挂满足功率要求的激光器,限制了激光系统应用。为克服现有激光系统应用和无人机负载能力方面存在的不足,基于无人机折转光路这一能量传输方式,设计一种无人机激光中继重定向能量传输装置及其相配套的地面部分,讨论不同聚焦策略,并针对不同聚焦策略给出仿真条件下系统效能分析,可以为激光系统折转照射和机动部署探索一条新途径。Ground-based laser systems are limited in their effectiveness due to obstacles and beam divergence.This limitation can be mitigated by using UAV platforms for close-proximity illumination.Nevertheless,the currently available unmanned aerial vehicles(UAVs)often lack the payload capacity to carry the lasers that meet the necessary power requirements,thus limiting the application of laser systems.To tackle this challenge,a UAV-based laser relay redirectional energy transmission device and its corresponding ground part are designed based on the energy transmission mode of using UAV to turn the light path.Different focusing strategies are discussed,and the system efficiency analysis under simulation conditions is given for different focusing strategies,which can explore a new way for laser system turning irradiation and mobile deployment.
