How to store and manage ADC values in a 2D array for FFT processing in an FMCW radar system
@Sterling You can create a 2D array where each row will represent the
fft_in values at a specific time, or “chirp index” as you’re calling it. For example, if you’re capturing 20 chirps, you’ll want a 20x512 matrix—20 rows for each chirp and 512 columns for the samples.9 replies
