摘要: 提出了基于经典谱估计的加权法以提高频率分辨精度。在序列长度一定时,与传统周期图法或BT法相比,本方法能显著地提高频率的分辨精度,且稳定性好,可靠性高。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,compared with the usual methods of periodogram and BT,and it is steadier and more reliable.
