A DCT is identical to a DFT, twice as long, of the input data concatenated with its mirror image. Data concatenated with its mirror results in symmetric data. Since a symmetric vector is strictly even, there are no odd (sine or imaginary) components in the DFT result. Just cosine (or real or even) components. dan burke catholic bioWebMay 26, 2024 · I am able to determine the accurate range of target after performing the first FFT. However, as I determine the 2nd FFT to get the Doppler response, the velocity is accurately determined. However, when I plot the contour map from the 2nd FFT, the range is doubled as compared to the initial user defined range. dan burn brighton and hove albion

"WebNov 20, 2024 · FFT is a clever and fast way of implementing DFT. By using FFT for the same N sample discrete signal, computational complexity is of the order of Nlog 2 N . Hence, using FFT can be hundreds of times faster than conventional convolution 7. Therefore, FFT is used for processing in the medical imaging domain too. " - Cst fft
