摘要: 本文在简要阐述弗门(Forman)卷积处理和墨芝(Mertz)乘法处理两种相位修正方法之后,着重介绍单边带付里叶变换频谱的相位修正的一种新方法;给出了详细的理论推导;列出了它对理论上模拟的干涉图函数和实际干涉图的应用结果,并将此结果与弗门的卷积处理后的变换结果以及双边带变换结果进行了比较,效果良好,而且计算速度快于弗门的卷积方法;说明了这种新方法不仅理论上是成功的,而且在实际中也是可行的。

Abstract: A new method for the correction of phase errors in the single-side band Fourier transform spectrum is presented. The spectra transformed by this method were compared with those by Forman's conyolution method and the double-side band FFT.The results showed that this new method is satisfactory and its computation speed is faster than the others.
