WebApr 10, 2024 · The radar transmits the FMCW signals and measures their reflection off the water’s surface. The radar measures the change in the distance by estimating the phase of the beat signal after the mixed frequency of the transmitted signal and the received signal. The phase of the beat signal can be expressed as Equation (8).
