Improved estimation of errors due to antenna geometry in RASS based on a radar wind profiler

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"-ope ration mode is performed. The calculation approach is based on solving the equations analytically for diffractive wave beams and takes into account di ffraction effects in the Fresnel approximation 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 negli gible for RASS based on a monostatic radar not only in the far-field but al so in the transition zone between the Fresnel diffraction and far-field ran ges at the lowest RASS operational heights.
