  "description": "This raster function performs three different calibrations for Sentinel 1 datasets, including beta nought and gamma, and outputs the calibrated dataset. The objective of SAR calibration is to provide imagery in which pixel values can be directly related to the radar backscatter of the scene. Though uncalibrated SAR imagery is sufficient for qualitative use, calibrated SAR images are essential to quantitative use of SAR data.<div><br />Typical SAR data processing, which produces Level 1 images, does not include radiometric corrections and significant radiometric bias remains. Therefore, it is necessary to apply radiometric correction to SAR images so that the pixel values of the images truly represent the radar backscatter of the reflecting surface. Radiometric correction is also necessary for the comparison of SAR images acquired with different sensors, or acquired from the same sensor at different times, in different modes, or processed by different processors.<\/div>",
