FLUCTUATIONS OF MILLIMETER-WAVE SIGNALS IN PROBING OF SOIL FROM LOWER HEIGHTS

摘要

The results of field experiments that devoted to study of fluctuations of signals reflected from soil at orthogonal polarizations and different antenna inclination angle. The peculiarity of the experiments is the small distance to the soil that comparable with dimensions of it irregularities and the use of two- dimensional signal processing in "time- frequency" domain. The data obtained is intended for development of super-near range radar sensor for agriculture machines.
