| 中文摘要: |
| 利用简正波理论,对海洋波导条件下的矢量反转镜空间相关特性进行理论分析,并利用10Hz～200Hz低频宽带信号进行仿真计算。仿真结果表明,当仿真信道与实际信道完全匹配时信道相关出现最大峰值,且峰值所在位置即为声目标所在位置。据此给出矢量反转镜被动定位仿真实例。 |
| 英文摘要: |
| By using the Normal Mode theory,the theoretical analysis of the spatial correlation property of Vector Time Reversal Mirror is made under the condition of sea wave guide,and the spatial correlation property is simulated with a broad band signal of 10Hz～200Hz.The simulation results show that a maximal peak value appears when the simulated channel is completely matched with the actual channel,and the position of the peak value is just the position of the acoustics target.Using the technology of Vector Time Reversal Mirror, an emulational example for target passive location is given. |
