ABSTRACT: In the present paper, we
have studied the effect of soil textures,i.e.,
sand, silt and clay on microwave scattering at X-band (10 GHz) at various
incidence angles and like polarizations (i.e., Horizontal-Horizontal;
HH-, Vertical-Vertical; VV-). We have proposed a retrieval technique based on
Genetic Algorithm (GA) to retrieve soil texture. For this purpose, ten types of
soil mixtures having different percentage of sand, silt and clay have been
analyzed. The observations were carried out by ingeniously assembled X-band
scatterometer. A good agreement has been noticed between estimated and observed
soil texture. Study infers that soil texture is quite sensitive to radar
scattering and it is possible to retrieve soil texture with radar/scatterometer
data with good accuracy and this type of retrieved results can be helpful to
predict soil strength as well as soil erosion of the particular area.
