| Abstract: | The FPr-FS spectrum zooming method is introduced. Without adding samples, accurate frequency in the related frequency scope is got. The method of fault diagnosis of missile structure using the spectrum analysis of vibration data is illustrated. It is demontrated by an example of diagnosis of missile structure that this method is effective. |
