The system transmits a continuous … WebJan 18, 2024 · Answers (1) For FMCW, after phased.ReceiverPreamp, that's the raw signal. You will need to mix it with the transmitted signal and then do an FFT to find the beat frequency. For LFM, the process is similar, but is more often referred to as stretch processing. You can use the stretch processor in the toolbox to find the beat frequency. sims 4 mods create a sim background
