| 摘 要： | 应用傅里叶退卷积、自回归模型与截断奇异值分解相结合的方法，获得了比采用常规变换方法高得多的光谱分辨率。与研究光谱超分辨率的其它方法相比，用ＦＡＴ方法进行了光谱超分辨率估计，有分辨率高，谱线细锐、钪噪声能力强和无伪峰等许多优点。

| Abstract: | A new method combining the Fourier self-deconvolution(FSD),autoregressive model(AR)and truncated singular value decomposition (TSVD) forsuperresolution estimating of Fourier transform spectra is discussed. Comparing to theother methods for the purpose of resolution enhancement, the method proposed in thispaper (as is called the FAT method) has the advantages of higher resolution, narrowerline shape, no spurious peaks and insensitive to noise. |
