Analysis and simulation of phase coherent acdar sounding measurements

摘要: The phase surface geometry and its dependence upon system atmospheric parameters for both monostatic bistatic acdar sounders is discussed. observed Doppler frequency shift shown to be a consequence of the motion with respect equiphase surfaces many distributed scatterers. Because measured average frequencies spectra are integral functions system-related structure-dependent weighting functions, application simple models that assume signal scattering only along antenna beam axis may result in significant wind velocity measurement errors. It further accurate quantitative estimates CT2 CV2 thin turbulent layers require detailed analysis common volume. Two techniques, based on scatterers random phasors, respectively, used simulating amplitude fluctuations.
