This work presents the validation of a modelling method for the characterisation of the VOR error in the presence of large scatterers. More specifically, wind turbines are considered because their increasing number makes their modelling a topical problem. Here, the electromagnetic perturbation due to the wind turbines is addressed by a method hybridising parabolic wave equation and physical optics. The VOR receiver is considered such that the overall method gives an estimation of the VOR error. This method is validated by comparisons with in-flight measurements performed in the same location before and after the erection of a wind farm.
