The paper describes the C-SAR instrument for the GMES Sentinel-1 mission. After a brief introduction a description of the overall C-SAR instrument as well as of the design and development status of its major subsystems (i.e. the SES Electronic Subsystem (SES) and the SAR Antenna Subsystem (SAS)) is given. The main focus on this paper is on the SAS, since there is a dedicated paper on the SES within the same session.
