边收边发技术可提高声诱饵对智能鱼雷的对抗能力，增强信号适应性。实现此技术的关键在于要降低声诱饵自身发射系统对水声对抗器材接收端的影响，避免器材自身发射系统发射的信号被接收机接收，因此有必要针对边收边发技术进行水声器材声隔离度获得方法的研究。研究利用发射和接收换能器的指向性和自适应噪声抵消技术可为器材带来的隔离度，并给出了仿真结果与水池试验结果。结果表明：利用发射、接收换能器指向性可获得30dB左右的隔离度，利用自适应抵消技术可获得15dB左右的隔离度，以满足边收边发的指标要求。

‘Receiving and sending’ technique can improve acoustical decoy’s ability for countering intellectualized tor-pedo, and also enhance the signal’s adaptability. The key of this technique is to reduce the effect of their own transmit-ting signal on the receiving signal, and to avoid receiving their own transmitting signal. So it is essential for this tech-nique to test the acoustic isolation degree of receiving from transmitting. In this paper, the isolation degrees achieved by the directivities of the acoustic transducer arrays for receiving and transmitting and by an approach called adaptive noise canceling are studied, the simulation and pool results are given. The results show that the isolation degree achieved by the directivities is 30dB, and the isolation degree achieved by an approach called adaptive noise canceling is 15dB, these results can satisfy the technical specifications of the‘receiving and sending’ technique.
