Validity Domain of the Odunaiya Expression for Computing the Conventional VOR Multipath Error

This work presents a method to determine the validity domain of the static Odunaiya expression for computing the VOR multipath error in the presence of wind turbines. The Odunaiya formula is considered valid when it gives the consistent response compared to a dynamic receiver model. This validity domain is then expressed in terms of the Doppler shift of the multipath with respect to the direct path. This leads to a geometric criterion that is illustrated.
