Fmcw radar range resolution equation

The range resolution of FMCW radar is proportional to the reciprocal of the bandwidth, i.e. delta x = c / (2 * delta f). You need to define this based on the tuning range of your radar's sweep oscillator.

What is the radar range equation?

kTB = -174 dBm/Hz

The radar range equation above can be written for power received as a function of range for a given transmit power, wavelength, antenna gain, and RCS.

How is radar range of resolution calculated?

Range resolution as a distance can be calculated as follows: R_res = c * τ /2 Where, τ is the transmitted pulse width and c is the velocity of light in the free space. Narrower beamwidth is very useful to distinguish two adjacent targets.

What is the meaning of radar range resolution?

Range resolution is the ability of radar system to distinguish between two or more targets on the same bearing but at different ranges. The degree of range resolution depends on the width of the transmitted pulse, the types and sizes of targets, and the efficiency of the receiver and indicator.

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.
