| Abstract: | In order to support real-time monitoring the position of a submarine in acoustical manoeuvre, low probability of interception （LPI） was analyzed from the aspects of detection ability and sonar equation. Contrastive study on LPI between the spread frequency signal and usual CW and liner frequency modulation signals was conducted and validated by computer simulation. The results show that the spread frequency signal has good LPI performance and detection ability. |
