| Abstract: |
| Lightning is one of the main natural sources of electromagnetic field in sea, and it will give serious influence to subaqueous weaponry. Because the duration of lightning is short, using classical spectrum estimation is hard to extract line characteristic of spectrum frequency. The Levinson-Durbin recursion algorithm based on autocorrelation matrix of output sequence was used to calculate parameter of AR model; power spectrum of the signal was calculated from the model. The result showed that LD algorithm can obtain correct line characteristic. |
