GMES Sentinel-1: SAR Calibration Algorithms, Part A of IN-11

Abstract

In the frame of the Global Monitoring for Environment and Security programme (GMES), ESA is undertaking the development of the Sentinel-1, an European polar orbit satellite system for the continuation of SAR operational applications in C-Band. This document provides the Sentinel-1 SAR calibration algorithms reflected by the so called Calibration Segment (CS) as part of the Sentinel-1 Payload Data Ground Segment (PDGS). This CS is composed of different sub-segments in order to implement the overall SAR system calibration strategy. The Sentinel-1 SAR calibration algorithms document identifies all requirements, procedures, algorithms as well as internal and external interfaces necessary to meet the SAR system requirements. This document does not include the overall calibration strategy.
