| Abstract: | 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. |

| Keywords: | Time reversal Self-focusing Passive detect Robust and stable |
