WebJul 17, 2024 · With a 1 / N normalization, the discrete fourier transform can be represented as the multiplication of a unitary matrix, thus the sum of squares is preserved. Z = F S. Suppose Z is a complex vector of the DFT bins, F is the tranformation matrix, and S is a complex vector with your signal. Of course, a real valued signal will fit too.

WebMay 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. WebMay 22, 2024 · The Fast Fourier Transform (FFT) is an efficient O (NlogN) algorithm for calculating DFTs The FFT exploits symmetries in the W matrix to take a "divide and conquer" approach.
