WebMay 8, 2024 · A Frequency Modulated Continuous Wave Radar or FMCW Radar system is a special type of radar system that measures both distance and velocity of moving objects. This is achieved by continuously varying the frequency of the transmitted signal by a modulating signal at a known rate over a fixed time period. Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing it to be detected by filtering out the transmitted fre…
