It is theoretically and experimentally shown how angular smoothing of the sky brightness temperature caused by the radiometer antenna pattern can be used in conjunction with the spectral characteristics of the amplitude scintillations of a beacon receiver to allow unambiguous determination of the wind speed of a turbulent layer and its height, helping in the estimation of the refractive index structure constant (Cn2).
