Figure 1: Ranging with an FMCW system
www.radartutorial.euFrequency-Modulated Continuous-Wave Radar FMCW radar is a special type of radar sensor which radiates continuous transmission power like a simple continuous wave radar (CW-Radar). In contrast to this CW radar FMCW radar can change its operating frequency during the measurement: that is, the transmission signal is modulated in frequency (or in ...
Guide to building a GPR radar for educational use ...
gpradar.euLike CW radar, FMCW radar uses Doppler effect, and can measure the speed of detected mobile objects. Moreover, FMCW radar exceeds the limitation of CW radar, regarding the possibility to measure distance of detected stationary objects, due to missing time reference. FMCW radar transmits signal which change periodically in the frequency.

Using a complex-baseband architecture in FMCW radar systems
www.ti.comfrequency-modulated continuous wave (FMCW) radar systems. Typical radar front-end implementations use a real mixer with a real baseband and analog-to digital converter (ADC) chain. However, there are performance advantages that can be leveraged with the use of a quadrature mixer and complex-baseband architecture in the context of FMCW radar.
