You don't know the first thing about it. Speed radar is measured using simple math. Some police officers even do the maths rather than have the gadget compute it. In the Navy, they call it the "Mo Board" of radar telling the speed and direction of a distant ship. This speed radar has been around since world war 2. Doppler shift has nothing to do with it. Look it up, for petes sake instead of spewing off the mouth. But you don't need a coarse on speed radar, you need a coarse on manners first.

Reflections are frequency shifted (Doppler shift) if the target is moving; the faster the target is traveling, the more the frequency shifts. A target traveling toward the radar shifts the frequency higher while a target traveling away from the radar shifts the frequency lower (compared to transmit frequency). The radar, by design, simultaneously transmits a continuous signal while receiving continuous signal echoes. Enrico

[...] Imagine the police radar is at rest and emits sine waves with crests one meter apart (a signal at about 300 Mega-Hertz). Suppose a mirror is moving away at 10% of the speed of light from the radar, in a radial (in-line with the signal) direction. When a crest advances 1 meter, the mirror recedes by 0.1 meter. The question is then what is the crest-to-crest separation after reflection off the mirror? This might involve special relativity, I'm not completely sure. But think about planets orbiting about far away stars. It's often said that as the earth-planet radial velocity varies as the planet moves in its orbit, periodic variations in spectral lines (wavelengths or frequencies) are measured, interpreted as Doppler effects. Don't you think this is well established? David Bernier

What puzzles me is: Why does he do this? What's so entertaining about it, that it's worth spending so much time on? And what draws people to keep trying to explain things, knowing full well that it's totally pointless, and that he'll never stop reciting his twisted arguments? He's been doing this for years! What's the point? I'd like to understand what kind of grotesque mind we have on our hands here. Jeroen Belleman

AP is his own Universe (as in, the Solopsist school, the original "many universes" school of Bishop Everrit) of pidgen circumlocution about all topics, BUT I do agree that an actual doppler interferonetry would not be needed for radar-ranging objects at close range, and even that "doppler radar imaging" of storms may not actually use the principle, or only *translate* it into a graphical representation that evokes doppler- gangers. the rest of his ****, seems to be scatology, or jsut English as a One-and-a-half language ... I mean, English as a second of two halves of two langauges, as he was adopted from immigrant parents, per his CV. thusNso: the poor man is insisting upon the base of ten, and that is guaranteed to be a barren approach, by all of the work of Fermatttt (Fermat's Little Theorem e.g.; of course, the theorem applies in any base, but ... y'know?). also, the simple idea of assuming that a^n etc. are rational, thence seeking a contradiction, is very well-illustrated in the literature; however, that is in English and other languages, that AP does not appear to know past Kindergarten. > Please post your proof, at last! thusNso: maybe AP has a good thought, that speed-trap radars have no need of using such a doppler shift, assuming that it does exist, because mere timing of the radar's return, over some part of a second, is adequate to do the math. and, one always hears of "dppler radar" by weather satellites, whether or not that *inerferometry* is actully required, and the radar-ranging can stil be interpreted in terms of doppler shifts (in the colors of the Weather Channel graphics e.g.). now, why AP does not "beleive" in doppler shifts, apart from the belief in the so-called Hubble *interpretation* of the prevailing redshift-woith-distance effect, seen in the starfield ... you'd have to read his ****, more carefully; and that, ladies & germs, is scatology. --Stop BP's and Waxman's capNtrade arbitrage rip-off! http://wlym.com |
