应用FFT方法计算时间序列平均周期的源码。不是很复杂，不过效果比较好。可供参考(Application of FFT calculated the average cycle time of the source sequence. Not very complicated, but the effect is better. For reference)

Many synthetic aperture radar (SAR) image formation algorithms require the computation of a multidimensional Fourier transform of irregularly-sampled or unequally-spaced data samples. We apply a recently developed algorithm, the unequally-spaced FFT (USFFT),2 to SAR image formation and compare its accuracy and complexity to a conventional algorithm. We find that the USFFT algorithm allows comparable accuracy to traditional approaches at a slightly reduced computational cost. We briefly discuss extensions of the USFFT algorithm to multiresolution SAR imaging
