How do you calculate radar resolution?
Range resolution as a distance can be calculated as follows: Rres = c * τ /2 Where, τ is the transmitted pulse width and c is the velocity of light in the free space.
How does FMCW radar estimate the distance?
FMCW radar systems measure the frequency difference (Δf, due to run time) between the transmitted and received echo signal for calculating the distance, and it also measures the Doppler frequency (due to the Doppler effect) for calculating the speed of the object.
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.
What is the radar equation?
The radar equation describes the physical power budget of a signal emitted by the radar from the moment it enters the transmitter antenna until it is received by the receiver antenna. At the beginning, the transmitted signal is generated by the radar emitter chain.
