摘　　要：描述一个新型的改进的快速傅立叶变换算法过程。该算法与传统的FFT算法有很大的区别,仿真中实现了提高时间利用率以及降低存储量。该算法的应用是基于现代微电子工艺集成度的提高以及优秀高速乘法器的处理性能,每个采样信号到达后直接进行运算处理为相应系数,整体提高了DFT算法系统的运算速度。The complicated environment for modern electronic counter and the appearance of new radar systems put forward a new＇lesson to sub-collect the signal and track the signal, especially in real time. With the background of high speed of signal acquisition a processing, the acquisition, the domain and frequency domain processing for the signal are researched and the related calculation methods of the FFT is discussed, the DFT possibility ofhaving the higher efficiency is analyzed comparing with FFT and a kind of DFT processor construction is put forward.
