How does FMCW radar work?
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.
What is FFT in radar?
When it comes to radar, the FFT (Fast-Fourier Transform) is used to convert time domain signals into frequencies. An example of its use is for converting the dual channels of a pulse-Doppler radar from time domain into range-Doppler data.
What's the difference between FMCW and CW radars?
The CW radar can measure the Doppler frequency of the target, but it cannot measure the target range. The frequency-modulated CW radar (FM–CW) can measure both the range and Doppler frequency of the target.
Which block is present to getting the value of range and Doppler velocity in FMCW radar?
Switched Frequency Counter − It is useful for getting the value of Doppler velocity. Average Frequency Counter − It is useful for getting the value of Range.
