The higher … WebSep 30, 2024 · FMCW Radar Automotive radar systems operate using a so-called Frequency Modulated Continuous Wave (FMCW). The system transmits a continuous wave at a certain frequency, which is then modulated over a period of time T. This gives the transmitted signal a “time stamp". The signal travels then to the target and part of it is …
