A rigorous theoretical consideration of the parameters of a received signal for a RASS based on a radar wind profiler and operating in the “Bragg”-operation mode is performed. The calculation approach is based on solving the equations analytically for diffractive wave beams and takes into account diffraction effects in the Fresnel approxim ation for both radio and acoustic waves generated by antennas with finite sizes. It is shown that the errors due to the displacement of an acoustic source and horizontal wind are negligible for RASS based on a monostatic radar not only in the far-field but also in the transition zone between the Fresnel diffraction and far-field ranges at the lowest RASS operational heights.
