引言随着科学技术的迅速发展,越来越多的科学技术部门要求对随机信息进行数据处理和实时分析。六十年代提出了快速福里哀变换的计算方法,相继出现了快速福里哀变换处理机,近年来,对快速福里哀变换的计算方法进行了大量的研究,提出了不少计算方法,它们对提高计算速度,提高计算精度上都有所发展,近几年来,也出现了不少快速数据处理机用于雷达、水声、地震、随机信息处理与控制领域中。
INTRODUCTION With the rapid development of science and technology, more and more science and technology departments are required to process and analyze real-time data with random information. In the 1960s, a fast Fourier transform algorithm was proposed, followed by a fast Forressee transform processor. In recent years, a large number of studies have been made on the computations of fast Fourier transform, and many calculation methods have been proposed, In recent years, there have been many fast data processors used in radar, underwater acoustic, earthquake, random information processing and control fields.
