Analyzing Backscattering Coefficient Using Monostatic scatterometer for Distinct Surfaces with HH polarization

Scatterometer are active microwave instruments which send electromagnetic pulses to the earth's surface and measure the dispersed signal back in its direction. This paper presents the design of monostatic radar in the frequency of 6GHz where the horn antenna is operating over the frequency range of 4-8GHz and to analyze the behavior of backscattering coefficient (σ0) for different roughness and moisture conditions at incidence angles (0) from 20o to 70o in a step of 5o each. This Antenna gives frequency range with unrealizable during a one device. Two antennas are mounted one upon the other in same or different polarizations. σ0 with respect to different 0 for different roughness and moisture conditions for the case of mono static scatterometer is analyzed with HH polarized antennas. A monostatic scatterometer, consisting of a transmitter and receiver kept one on the other, was developed indigenously for this purpose. Complete setup is designed with a movement wheel and also to alter incidence angle of the antennas. In areas such as the dielectric behavior of medium ruggedness moisture content texture the subsurface tends to shift. Changes in roughness and moisture how it effects the backscattering signal behavior is investigated.
