Live Pinpoint Weather 12 Radar & Satellite. You have been added to WPRI Pinpoint Weather 12: Weather Alerts Newslette A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to.

Even though police radar is based on the Doppler Principle, most units do not interpret the Doppler shift itself. Rather, they process the frequency of the signal and use its analogy to represent target speeds. Known as phase-lock loop, or PPL, this processing can lock onto the wrong target, double or triple low speed readings, or produce. SkyTower Radar: Hudson & West Pasco. Animated radar view of western Pasco County, including the communities of Hudson and Port Richey Police Doppler Radar. Police microwave radars all use the Doppler Principle to measure speed. The radar transmits a continuous microwave signal and simultaneously measures the echo that is frequency shifted proportional to speed, the Doppler Shift. The frequency shift is measured in cycles per second and has unit dimensions of Hertz (Hz) These methods are called double-Doppler (from 2 stations) and triple-Doppler (three stations). If you probe any given patch of sky with two radar beams from different locations, then you can work out exactly how the rain is moving in two horizontal axes with relatively simple geometrical methods GMWR-400/1000-SST.
