Physical Scattering Mechanism of Synthesis Aperture Radar (radar Sat-2) by Using Polarimetric Analysis Method to Identify Water Bodies over Earth Surface

Synthetic Aperture Radar (SAR) is one of the active microwave sensor that can capture the Electromagnetic Radiation signals of the physical objects. The ability of the microwave sensor to work in day and night is one of the major advantages and very useful in this technique. The capturing of scattered signals from SAR by using polarimetric process is applied to analyze distribution of various object types in the South Parambikulam region of Kerala. The study area contains water bodies, forest, vegetation and soil cover. There are many type of scattering methods available for SAR applications, those are multiple scattering, volume scattering, double bounces scattering and surface scattering. Depends on the scattering nature, it is possible to interpret the different types of object bodies. The SAR image used in this paper has taken from the RADARSAT-2 satellite.
