1. KOMPSAT-5 SAR INSTRUMENT OVERVIEW
KOrea Multi-Purpose SATellite (KOMPSAT-5, hereafter) mission objectives are the provision of SAR images for Geographic Information Systems applications, and the Korean national environment and disaster monitoring System. The mission orbit is circular and the satellite altitude is 550 Km.
The KOMPSAT-5 SAR payload includes X-band (9.66 GHz) Synthetic Aperture Radar with a fixed antenna capable of electronic steering both in the azimuth and the elevation planes.
The elevation steering capabilities, allows defining an access region spanning approximately from 18.3° up to 49.0° in terms of the corresponding off-nadir angle (20° - 55° incidence angle @ 550 Km). Such range includes one nominal access spanning approximately from 18.3° up to 40.6° in terms of the corresponding off-nadir angle (20° - 45° incidence angle @ 550 Km) in which nominal performance are granted.
The SAR is designed to implement different types of Image Operation Mode that are briefly detailed in the following paragraphs.

The SAR is capable of operating in three measurement modes: Standard Modes, High Resolution Modes and Wide Swath Modes. Each mode provides different

characteristics in terms of ground sample distance (i.e. geometrical resolution) and swath-width.
The “K5 System Enhanced” foresees the enhancement of SAR P/L with four additional operative modes:
 EH : Enhanced High Resolution mode
 UH : Ultra High Resolution mode
 ES : Enhanced Standard mode
 EW: Enhanced Wide Swath mode.
