摘要
叙述了常用的Ｍｅｒｔｚ法的基本原理并进一步讨论了其中的计算效率问题，通过利用实序列离散傅里叶变换的性质与相位校正的具体的处理内容相结合，优化了Ｍｅｒｔｚ法的计算处理，提高了计算效率．
The correction of phase error is an important step in the calculation of Fourier transform spectrum. The problem of computation efficiency of the commonly used phase correction method, Mertz method, is studied in detail. By applying the quality of real serial Fast Fourier Transform (FFT) and combining it with the computing process, an improved algorithm is obtained, which demonstrates greater computation efficiency and is easier to use.
