Abstract

The line spectrum detection method based on coherent power spectrum estimation is one of the important research directions of weak line spectrum detection. Aiming at the problem that the phase compensation in the line spectrum detection is not accurate due to the limited frequency search accuracy of the existing coherent power spectrum estimation methods, a line spectrum coherent detection method based on cross-spectral frequency measurement (CDCSFM) is proposed on the basis of the CAPSE method. The cross-spectrum method can more accurately estimate the line spectrum frequency, and then perform more accurate phase compensation and further improve the coherent processing gain. The simulation results and sea test results show that the coherent processing gain of the CDCSFM method has a certain improvement compared with the CAPSE method.
