| Abstract: | This paper raises the theory and method using add-weight to heighten frequen resolving precision based on classical spectrum. Results show that the method can notably enhance the resolving precision of frequency under the certain length of array,compered with the usual methods of periodogram and BT, and it is steadier and more reliable. |
