  1. What is the range of FMCW radar?
  2. What is resolution in radar system?
  3. Which block is present to getting the value of range and Doppler velocity in FMCW radar?

What is the range of FMCW radar?

Frequency Modulation is used in FMCW radar. FMCW radars use mm wave electromagnetic spectrum which has very short wavelengths upto 4 mm [9], [10]. The frequency used is in range of 76–81 GHz. Higher frequencies are used so that even smaller objects can be detected effectively.

What is resolution in radar system?

The minimum separation between two targets that permits them to be distinguished by a radar. The minimum separation in range along a given direction from the radar is one-half the transmitted pulse length. The minimum angular separation at a given range is approximately the 3-dB beamwidth of the radar.

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.
