Research on the detection and separation of acoustic signals of low altitude targets based on passive acoustic detection is done.Influence factors while detecting the acoustic signals are introduced.Emulation signals are separated by FastICA,one of the methods of blind source separation.Measured purer acoustic signal of some altitude target is mixed with noises and then separated by FastICA.The two signals are separated properly.The results show that FastICA has advantage on the separation,especially on the...
