Abstract: 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.
