谐波检测中的加窗算法研究
Study of Harmonic Analysis Windowed FFT Algorithm
傅里叶变换在理想条件下对于稳态信号的分析有较高的精确度，但实际情况下会存在频谱泄露，本文针对其频谱泄露的实际情况，引入加窗算法，对常用余弦窗函数进行比较，并在其基础上引入基于二阶海宁卷积窗的加窗算法用来减少频谱泄露，使得对稳态信号分析的精确度大幅提高。
In ideal condition Fourier transform have high accuracy for steady-state analysis of signal, But in the actual circumstances will exist spectrum leakage, the paper according to the actual situation of the spectrum leakage Introduce the Window Algorithm, so compared to common window functions, and introduce of Interpolating 2-Order Haining Window algorithm used to reduce spectrum leakage,to improve the accuracy of the steady-state signal analysis.
