Liu C. Perfection of models and methods for radio acoustic and acoustic sounding of atmospheric boundary layer

Object – processes of interaction of acoustic waves with an inhomogeneous moving medium and the scattering of electromagnetic waves in beams of acoustic waves. Aim – development of theoretical bases of acoustic and radio acoustic sounding (AS and RAS) to improve the models and techniques and more informative sounding of the atmospheric boundary layer (ABL). Methods –turbulence theory, the propagation of acoustic waves, diffraction of radio waves by complex objects, numerical and simulation. Results –analytical expression for the spectrum of signals in AS, improved physical models and methods by AS before the effect of adiabatic changes in density and offset air propagation path AS, the solution of the diffraction problem for the lower slopes bistatic sensing system once. Implementation – in the research activity carried out at KNURE. Application – development of sounding systems ABL
