Characterization of cross polarization discrimination in forest environments

This paper describes short range UHF dual polarized, dual frequency, radio propagation measurements performed in a forested environment using low antenna elevations. The 2×2 polarization matrix was investigated in terms of path loss, cross-polarization and fading statistics. The results show a higher depolarization of the vertical polarized signals at higher frequency. No significant power correlation coefficients were measured for tramsmitter-receiver distances larger than 150 m. The short term fading depends on the receive antenna polarization and is less predictable at lower frequencies
