摘要
从信道理论出发研究了时间反转镜的聚焦效应,提出时间反转镜空间滤波技术,对其空间匹配特性、处理增益、检测能力、稳健性作了仿真研究。仿真结果表明,利用了海洋信道的相干多途特性,时间反转镜可实现信号的空间匹配滤波,从而对目标进行检测,检测能力强。
The time-reversal mirror's refocus effects are studied based on the point of view of the channel theory, particularly, Time-reversal Mirror (TRM) space filtering technology is introduced in this paper. The simulation results of TRM's spatial match characteristic, processing gain, detecting ability and robust behavior show that this technology produces focusing in space and has higher detecting performance.
