| Abstract: | Adopting field-programmable gate array(FPGA) to implement the fast Fourier transform(FFT) algorithm may increase the real-time responsibility of signal processing.Aiming at the spectrum analysis of high velocity wideband signal,this paper presents a kind of realization method to calculate the FFT of the 1M points using FPGA,and tests & validates the calculation result.The harvest is also suitable for the analysis of the fine characteristics of the narrowband signals. |
