Doppler Radar Tracking Using Moments
Mohammad Hossein, Hamidreza R. Amindavar · InTech eBooks · 2012
A Doppler radar is a specialized radar that makes use of the Doppler effect to estimate targets velocity. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object’s motion. This variation gives direct and highly accurate measurements of the radial component of a target’s velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns, radiology, and bistatic radar (surface to air missile).
