“…The polarization cross-coupling aspect was less studied and mostly related to radar scattering investigations [12], [8], [17]. Complex, deterministic pathloos models were obtained using the electromagnetic field theory for one [6], two-three [13], [9], or four [7] layered approximation of the vegetation. Other methods are based on stochastic modelling of the vegetation scattering [16], [2].…”

The 2x2 polarization matrix was investigated in terms of path loos, cross-polarization and fading statistics. The results show a higher depolarization of the vertical polarized signals at higher frequency. No significant power correlation coeficients were measured for tramsmitter-receiver distances larger than 150m. The envelop short term fading depends on the receive antenna polarization and is less predictable at lower frequencies.
