摘要：
A synthetic-aperture multifrequency polarimetric radar complex is used for experiments on studying the features of reflection of electromagnetic waves from pine forests. It is found that the intensity of the reflected power is proportional to the biometric characteristics of the forests. The hydrology and spatial fluctuations of the dielectric characteristics of the upper layer of the forest soil are studied at different depths. It is shown that spatial fluctuations of the soil's dielectric characteristics can be used to explain the features of reflection from the forest. Reflection from a forest in the meter wave band at horizontal (HH) and vertical (VV) polarizations is simulated. It is found that mechanisms of reflection from the forest may be different for the HH and VV polarizations. Experimental data confirming the presence of specific effects in the radar images obtained in the meter wave band at the HH and VV polarizations are presented.
