Perform radiometric calibration of SAR images. Following sensors are supported: TerraSAR-X,
Sentinel1 and Radarsat-2.Both Single Look Complex(SLC) and detected products are supported as
input.
The objective of SAR calibration is to provide imagery in which the pixel values can be directly related to
the radar backscatter of the scene. This application allows to compute Sigma Naught (Radiometric
Calibration) for TerraSAR-X, Sentinel1 L1 and Radarsat-2 sensors. Metadata are automatically retrieved
from image products.The application supports complex and non-complex images (SLC or detected
products).
This section describes in details the parameters available for this application. Table 4.42, page 488 presents a summary of these parameters and the parameters keys to be used in command-line and programming languages. Application key is SarRadiometricCalibration.
