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 a range Doppler plot?
FFT Plot (Range-Doppler Plot): The FFT is used to convert radar time domain data to frequency domain. Detected objects and their Doppler signature are plotted in an FFT Plot. The x-axis represents the Doppler Frequency (which can be converted to Doppler Speed), and the y-axis is range.
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.
What is range Doppler algorithm?
RCMC is performed in. range frequency and azimuth frequency domain. Since, azimuth frequency is affected by. Doppler Effect and azimuth frequency is bonded with Doppler frequency, it is called. Range Doppler Algorithm.
