摘要
针对快速傅里叶运算中分辨率必须以提高采样时间为代价的问题,提出通过对过往数据的简单变换利用,增加了一次快速傅里叶运算的点数的快速傅里叶算法。该算法达到了在不改变采样时间的前提下提高分辨率的目的,仿真表明最终使得分辨率可以提高2到4倍。
A new FFT algorithm being able to increase sharpness of separation of FFT without extending sam- pling time was proposed in this paper. The algorithm could increase sharpness of separation of FFT at the same sampling time by using passing data. In theory, sharpness of separation could be twice to four times as much as before.
