为了理解何为重叠处理,首先可以看下图。 观察到一段数据记录完成后,立刻进行FFT处理,其中信号采集的时间比FFT计算时间长得多。仔细观察便可发现,当一个FFT处理流程结束后,大部分时间都处于闲置状态。如果此时不是等待一个全新采集信号,而是将目前...
SAR image processing For the implementation of an FFT, in space grade technology there are only a few options. One can implement a FFT in a general purpose processor but these are to slow to cope with the instrument data generation. Implementing an FFT core in a space grade FPGA like the...
Part Number:IWR1642 Hi all, I'm usingDCA1000EVMto capture the raw data of IWR1642, and I wonder if I can use the raw data to get the range-doppler map. So is there any detail about the FFT processing? Hi, Q1) can use the raw data to get the range-doppler ...
An efficient operation applied prior to fast Fourier transform (FFT) processing is described that enables one to obtain the same spectral resolution with shorter FFTs. This so-called prefolding operation is complementary to zero fill. Both techniques are described. 机译:描述了在快速傅立叶变换(FFT...

Hello! I use FFT + IFFT pair, my adc is 12 bit and Vp 3,3 Volts, input signal is sin Amp 400mv DC offset 800mv, i have right amplitude spectrum after FFT (the square root of the sum of squares х 2, exactly DC component) . Now i add IFFT to my project, connect sour...
In this paper, we present a new fast Fourier transform (FFT) algorithm to reduce the table size of twiddle factors required in pipelined FFT processing. The table size is large enough to occupy significant area and power consumption in long-point FFT processing. The proposed algorithm can reduce...
