What is Doppler resolution in radar?
This page mentions what is Doppler Resolution. It also mentions equation of Radar Doppler Resolution. This is the ability of radar to differentiate targets or objects which are located at the same range but are moving at different radial velocities.
How is Doppler resolution calculated?
The resulting velocity resolution δvr = λ/(NpTp) depends on the radar wavelength, the pulse repetition period, and the number of consecutively sampled echoes. The largest Doppler shift that can be measured without aliasing is and defines the maximum unambiguous velocity vNy = λ/(4Tp).
What is the resolution of radar?
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.
How do I increase the resolution of my Doppler?
Range resolution was obtained by using a short pulse and by frequency or phase modulating it in order to increase its frequency bandwidth. On the other hand, velocity (Doppler) resolution can be improved by increasing the time duration of the pulse.
