Watch an introduction to Frequency Modulated Continuous Wave (FMCW) radar and why it’s a good solution for autonomous vehicle applications. This demonstration will show how FMCW radar can measure range and radial velocity for multiple targets at once using the Doppler effect, beat frequency, and frequency modulation.
