Which modulation techniques are used in radar systems?
Modulation techniques play a key role in in radar technology. The mode of transmission makes a huge difference in the performance of radar and hence the technique will change as per the application. The two most commonly used techniques are Frequency Continuous Modulated wave (FMCW) and the Pulsed Doppler technique.
What is frequency modulation in radar?
Frequency Modulated Continuous Wave (FMCW) radar is a form of radar where the frequency of the transmitted signal is continuously varied at a known rate over a defined time period. The reflected frequency signal is received by the radar and compared.
What is modulated radar?
Modulated continuous-wave. Frequency-modulated continuous-wave radar (FM-CW) – also called continuous-wave frequency-modulated (CWFM) radar – is a short-range measuring radar set capable of determining distance.
What is the principle of FM radar?
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.
