A 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.

WebbAs a consequence, it is clear that σQ is a property that (approximately) characterizes a specific target, not the radar system and/or its interaction with the target. In this case, the simulation of σQ for the proposed design of a vehicle will provide a good estimate of its “radar invisibility.” WebbPower spectrum and power spectral density are agnostic to the type of signal that is used to generate an intensity distribution in the frequency domain.
