Abstract.
We consider the method of determination of
effective permittivity of forest growth in low frequency part of VHF. The base
of the method is the analysis of experimentally obtained distance dependencies
of signal level in forest stratum. The purpose is the determination of
trajectory of side waves, sliding along upper forest border, when receiving and
transmitting antenna are embedded into the forest stratum. The obtained results
are in good correlation with known values of forest stratum permittivity,
obtained by another methods.
