The Effects of Soil Moisture on Bistatic Clutter Power.
Abstract
A major question for rough surface scattering analyses is how moisture affects the results. This study represents an extensive discussion of moisture effects in bistatic scattering. Considerable emphasis is placed on the roughness dependence of the effects. Comparisons are presented that show that the standard simplified bistatic model tends to suppress some of the effects and differs considerably from a more complete analysis. The effects of successively increasing the relative moisture levels are shown. A number of antenna power patterns are considered and the effects of relative heights and separation of the antennas are discussed. Finally, the basic study is extended to other system parameters. These include signal frequency and polarization. The relative effect of the moisture is found to be sensitive to these factors and, particularly, to the surface roughness. Originator-supplied keywords include: Electromagnetics, Moisture content, and Dielectric constants.
