The distance is proportional to the frequency offset between the transmitted signal and the received echo. Suppressing road clutter is important for automotive radar signal processing to detect targets, which requires accurate spectral distribution of clutter. The FMCW waveform is a common choice in automotive radar, because it provides a way to estimate the range using a continuous wave (CW) radar. The returned signal is similar in shape to the transmitted one, but shifted in time as the two-way trip from the radar to the target takes an amount of time t that is proportional to the distance to the target R: Radars based on a frequency modulated continuous waveform (FMCW) is the key technology used in most automotive radar applications today.
