An Application Of Circular Polarisation For Risat-1 Imagery Analysis In Rajastan Area
RISAT is a multi resolution, multi polarization and multi mode Indian microwave satellite that is capable to
operate in day, night and all weather conditions. It has an active micro remote sensor that provides for cloud penetration and
day-night imaging capability. These special nature of C-band synthetic aperture radar (SAR) enables applications in
agriculture, particularly paddy monitoring in kharif season and management of natural disasters like flood and cyclone.
Generally SAR backscattering behavior depends upon the sensor parameters like frequency, polarization and incidence angle
as well as on target parameters such as dielectric constant, roughness and geometry. In this paper we propose to calculate the
kappa statics for the classified image with help of circular polarization waves.
