The sensor ensures accurate detection of even the smallest movements.
What does FMCW stand for?
The abbreviation FMCW stands for Frequency Modulated Continuous Wave radar. It is a type of radar sensor that emits a continuous transmission signal and can change its operating frequency during measurement. What does this mean in practice? The transmitted signal is frequency modulated, making it possible to measure both the distance and the speed of moving objects. FMCW radars are used wherever it is necessary to measure very small distances and high measurement reliability is required.
