Web28 mag 2011 · The maximum negative Doppler frequency (fastest opening rate) at 10 GHz / 3 cm is: Radar-bearing aircraft minimum speed: 300 mph = 134 m/s. Effective radar-bearing aircraft minimum speed with θ = 60 degree angle from target track (sin (60) = 0.5): 150 mph = 67 m/s. Target aircraft maximum speed: 1200 mph = 536 m/s. WebA typical Doppler spectrum for a resolution volume within a thunderstorm is plotted in Fig. 6.8. This spectrum is obtained from a Fourier transform of 64 samples weighted with a von Hann window. The unambiguous velocity in this example is 28.5 m s −1, therefore the spacing of the spectral coefficients is 0.9 m s −1.
