【摘要】 在基于时间反演的空间功率合成系统中,由于电子器件制造工艺以及变频器件会引入随机相位误差,因此各个分布式功率合成装置产生的反演信号无法在目标处准确地实现同相叠加。针对此问题,本文提出基于参考信源相位同步的方法对能量合成装置进行相位校正,相对已有的旋转矢量法,信源相位同步方法具有抗干扰能力强且精度高等优点。更多还原

【Abstract】 In time reversal-based spatial power combining systems, random phase errors introduced by electronic component manufacturing processes and frequency conversion devices prevent the reversed signals generated by distributed power combining units from achieving accurate in-phase superposition at the target location. To address this issue, this paper proposes a phase correction method for energy combining devices based on reference signal source phase synchronization. Compared to existing rotating vector methods, the proposed phase synchronization method demonstrates stronger anti-interference capabilities and higher precision,enabling effective phase alignment optimization for distributed power synthesis systems.更多还原
