Abstract
The convergence of polarimetric scattering parameters and H, α and A features of road surfaces under various conditions is analysed. It is shown that the number of radar measurements used for surface classification can be traded off with accuracy of the estimation of the mean value and covariance of S-parameters and H, α and A features. Furthermore, it is shown that the H, α and A features converge at the same rate, independent of antenna orientation angles or considered road surface conditions.
