为了解决雷达信号处理中大点数脉压问题，将一维大点数FFT拆成二维实现。首先给出大点数FFT变换的数学原理，然后以96 K点为例，介绍了其在通用处理器ADSP-TS201的实现过程。测试结果表明，所提出的处理方式不仅能正确实现大点数FFT变换，而且具有较好的实时性。

In order to solve problem of great number of points pulse compression in radar signal processing, 1 di-mensional great number of points FFT can be realized by splitting it into two-dimension. The mathematical princi-ple of great number of points FFT is given firstly, then by taking 96K points as an example, the implementation process in general processor ADSP-TS201 is introduced. The test result shows that the proposed processing way not only realizes great number of points FFT correctly, but also with excellent real-time property.
