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: 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 ...

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

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 ...

An orbiting radar operates on the same principles as one tracking planes at an airport. The spaceborne antenna emits microwave pulses toward ... Called the Doppler shift, it's the same effect ...

France has provided Ukraine with trailer-mounted Crotale air defense systems, enhancing the country's capabilities against ...

When NASA and the Indian Space Research Organisation’s (ISRO) new Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar) ...

The programme is likely to be held this month or March at the doppler weather radar facility in the city. Institution-recommended candidates are required to mail their details to dwr.chennai@imd ...
