SOPHOS - Smart Onboard Processing for Earth Observation Systems D1.1 - Use Cases, Applications and Technical Requirements Report

Abstract

This document gives a description of the envisioned use cases and applications that are used as a foundation for the developments in the SOPHOS project. Additionally, the high-level requirements are derived from the reported use cases. This document starts with a survey of SAR applications and current missions and sensors. The survey covers both, institutional SAR missions (Copernicus program of the EC, national SAR missions like TerraSAR-X/TanDEM-X) and commercial activities (e.g. ICEYE). Parameters of a so-called SOPHOS reference SAR sensor are established to reflect the suspected very near future characteristics of an individual SAR sensor in a commercial constellation. For the design of the SOPHOS demonstrator we present a survey on the state-of-the-art and key enabling technologies. The document concludes with the summary of the high-level requirements to be met by the SOPHOS demonstrator.
