Order For Fft Method

The information that sensor-fuzed munitions received comes down to Fast Fourier Transform (FFT) about the analysis of power chart in the research of image disposal and signal processing of sensor-fuzed munitions. In this dissertation, a new rule is brought forward according to actuality of the taxis of FFT through investigation, analysis, test and deduce, what's more, this new rule is applied to the taxis of FFT. The standard program is upgraded by C language instead of FORTRAN language and modified according to the new rule, furthermore the efficiency of calculate is compared about the new arithmetic and the old one. This program is tested and the result indicates that this new program can boost 40 percent of calculate efficiency. It is very important to enhance calculate efficiency of taxis of FFT, and that, it is also significance to increase the calculate efficiency of image disposal and signal processing of sensor-fuzed munitions and to improve capability of real time and veracity of punching bag.
