WebFeb 8, 2024 · FMCW radar: understanding of doppler fft. I am using fmcw radar to find out distance and speed of moving objects using stm32l476 microcontroller. I transmit the … WebMay 28, 2024 · I have theoretical knowledge but I just started Matlab implementation of the same. Also I am completely new to the FMCW tool chain. I have to create an FMCW signal, transmit, receive and mix them to get the IF signal, and inturn get the radar 2D matrix for post processing. But I my 2nd FFT doesnt give the correct value of velocity.
