| Abstract: | A technique is introduced in this paper,which catches active sonar signal through timing detecting and frequency detecting,the flow of the technique is discussed in detail.And the transmiting distances of one way and both way are estimated in the same condition.The result of estimate makes clear that the detecting distance adopting this technique is exceeded the detecting distance of initiative sonar,consequently,long-distance detecting is realized. |

| Keywords: | active sonar signal catching transmiting distance long-distance detecting |
