| 摘 要： | 时反法是一种新颖的自适应聚焦技术，它可以使声信号在未知环境下实现时空聚焦。海洋是一个复杂多变的信道，它会使声信号产生畸变从而降低通信系统的工作性能。分析了时反法的理论基础，并对其用于浅海被动通信进行了仿真研究。仿真结果表明，它可以使信号实现重构，消除码间干扰，提高通信系统的性能。

| Abstract: | Time reversal is a unique self-focusing technique for spatial and temporal focusing of sound in unknown environments. Ocean is a complicated and changeable channel which may distort the signals and degrade the performance of communication system. Time reversal principle and its application to passive communication were introduced. The simulation result shows that this technology can reconstruct signal and erase intersymbol interference, so that the performance of communication system is improved. |

| Keywords: | Time Reversal (TR) adaptive self-focusing passive communication modeling simulation |
