Determining something's radial velocity—how fast it is moving towards or away from you—is quite easy. By taking note of something called the Doppler effect and making close observations of the ...

due to inherent limitations in the Doppler radar technology. RF stands for "Range Folding". The true wind direction can be determined on a radial velocity plot only where the radial velocity is ...

When a coherent pulse train is reflected by a moving object, the lines of the spectrum are Doppler frequency shifted an amount proportional to the object's radial velocity. When a number of objects ...

Chapter 11: Observation of Moving Targets by an Airborne Radar A doppler radar is defined by [1] as a radar which uses the doppler effect to determine the radial component of relative radar target ...

Finding a “Vulcan”-like planet, known in Star Trek lore as Spock’s home world, around the star 40 Eridani A, was thrilling.
