| 英文摘要: |
| The extraction problem of low frequency line spectrum of VLA tracking target is studied. A complete VLA low frequency line spectrum fusion extraction method is proposed. It is proposed that the mean square error multiplied by a scale factor can be used to set the threshold. Spectral components, and the use of high-signal-to-noise ratio line-spectrum direction-finding method to eliminate the interference line spectrum method to accurately extract the target feature line spectrum is studied, which effectively solves the problem of mutual interference of low-frequency line spectrum features of VLA port and starboard targets. Simulation and sea trial data verify the effectiveness of the proposed method. |
