| Abstract: |
| Reverberation is the main interference in active sonar system. Vector hydrophone is an advanced underwater acoustic measuring equipment, which received reverberation and signal of different phase. Based on the difference, the feasibility of using vector acoustic energy stream method for anti-reverberation was discussed. Theoretical study showed that this method can get high space processing gain and time processing gain. The result of calculation and simulation showed that vector acoustic energy stream method has better anti-reverberation than conventional pressure integrated square method. |
