摘要

时间反转(TR)技术用于具有多个未知位置目标的微波功率传输系统。在TR-MPT系统中，时间反转镜(TRM)阵列接收目标发射的探测信号，再将时间反转的信号与高能电磁波进行卷积，然后将电磁波能量集中到目标上。研究了三种不同目标位置的情况。与传统MPT系统中目标接收到的能量相比，TR-MPT系统中目标接收到的能量更多。结果表明，TR技术可用于提高多目标MPT系统的性能。

Microwave power transmission for multi-targeting antenna using time-reversal technology

Time-Reversal (TR) technology is used in a Microwave Power Transmission (MPT) system with multiple unknown-position targets. In the TR-MPT system, the Time-Reversal Mirror (TRM) array receives detecting signals emitted from the targets and re-emits the time-reversed one convoluted with high energy electromagnetic waves, and then the electromagnetic wave energies are focused on the targets. Three cases with different target positions are studied. Compared to the energies received by the targets in a conventional MPT system, more energy can be received by the targets in the TR-MPT system. The results show that the TR technology can be used to improve the performance of a multi-target MPT system.
