When these pulses intercept precipitation ... Most radars can measure reflectivity but you need a Doppler radar to measure velocity. Some 40 years earlier in 1842 the Austrian physicist Christian ...

Abstract: A method based on data extrapolation is proposed to enhance Range-Doppler resolution of ground ... to construct the radar returns with larger bandwidth and more pulses. This method consists ...

Doppler radars measure the phase of each pulse of energy as it returns to the radar, and any changes in phase can be related to motion of the reflecting particles. This is a similar effect to the ...

Abstract: Pulse Doppler radar techniques are widely used in modern radars to distinguish moving targets from clutter, often with complex adaptive signal processing. Research into the exploitation of ...
