Abstract: PURPOSE: A device of generating efficient testing signals for meteorological radar is provided to reduce time and cost designing the signal and data processor of a meteorological radar by analyzing and digitizing the conditions of the radar system on the doppler spectrum. CONSTITUTION: I(Inphase) and Q(Quadrature) signals received by a meteorological radar are electronic signals reflected off bits of rain and dust within the range cell. A mathematical method of a doppler spectrum caused movements of these bits is complex but possible to be described analysis. And the total doppler spectrum is obtained by adding all the doppler signals caused by reflections off all the bits. Thus, the form of the doppler spectrum is predicted to have a gaussian distribution applying the central limit theorem. The data obtained by observing doppler spectrums confirms that most of the doppler spectrums have a form of symmetrical gaussian distribution. But about 25% of doppler spectrums could not be described by the gaussian model. So a normalized skewed gaussian model is proposed to include both the symmetric and asymmetric gaussian doppler models.
