摘要
针对低功耗的无人机中继通信场景下,现有波束对准方法未考虑吊舱多面阵阵面部署、阵元数目静态不变等问题,为保证波束对准的高精度和低时延,提出了一种基于FPGA的波束对准实现方法;利用模拟位置和姿态信息进行坐标转换,在常规波束对准框架中引入多面阵协同的阵元规模动态可变参数,通过波束形成原理计算角度和移相值,最终FPGA返回数据,完成波束对准验证;仿真结果表明,在半波束宽度为12.7°的70个时隙中,角度误差维持在1°左右,功耗相比传统算法降低5%以上,波束对准时间为123.3μs;通过基于FPGA的硬件验证,证明了算法的工程实用性。
To address the limitations of existing beam alignment approaches in low-power unmanned aerial vehicle(UAV)relay communication systems—which neglect practical deployment configurations of pod-mounted multi-panel phased arrays and fixed-element architectures—an FPGA-based beam alignment implementation framework is proposed.By integrating simulated position and attitude data through coordinate transformations,the methodology introduces dynamically reconfigurable antenna element scales within a multi-panel array coordination architecture.Utilizing beamforming principles to compute angular parameters and phase shift values,the system achieves beam alignment through hardware validation on a field-programmable gate array(FPGA).Simulation results demonstrate that over 70 time slots with a half-beamwidth of 12.7°,the proposed method maintains angular errors below 1°,achieving a power consumption reduction of over 5%compared to conventional algorithms.Notably,the beam alignment latency is measured at 123.4μs.Hardware validation based on the FPGA platform further confirms the algorithm's engineering practicality,validating its robustness in real-time UAV relay scenarios.
