File talk:Radar-Dilemne Doppler.png

There's a conflict between the image's caption and the blue line on it. If you calculate out the required wavelength for the first unambigous radial velocity (first blind speed), which is V=(wavelength)*PRF/4, you discover that the caption has a rounding error. Instead of a 5 cm wavelength, it's really 5.33333 (repeating), or 5 and one-third. This shifts the frequency of the radar from 6 GHz down to 5.625 GHz. For a 5 cm wavelength, the Velocity axis would have the numbers every at 1.875 m/s; i.e. 1.875, 3.75, 5.625, 7.5, 9.375, 11.25, 13.125 and 15. A replacement image with a corrected caption or velocity values would fix this error. Also, "DILEMNA" is a misspelling. 138.163.0.44 (talk) 22:36, 15 July 2008 (UTC)
