A computer simulation of scattering from inhomogeneities in the refractive index is used to compare the spaced antenna and interferometer methods for measuring winds in clear air, both with and without turbulent fading. The results show that the spaced antenna analysis which is carried out in the time domain and the interferometer analysis which is carried out in the frequency domain are equivalent in terms of the information that the two methods yield. A data analysis method, equivalent to full correlation analysis, which can be carried out in the frequency domain is presented. The method is applied to model‐generated, simulated data in order to extract the typical full correlation analysis output parameters such as the apparent and true velocity. The results obtained are consistent with the model input parameters.
