Advanced Ocean Color Monitor (OCM) Feasibility Study

摘要

A modular pushbroom design for the ERS-2 Ocean Color Monitor (OCM) was assessed. Signal analyses evaluated the radiance at the entrance of the instrument, taking into account the sunglint contribution, instrument performances and interfaces, and instrument subsystems. A development plan and assembly, integration, and tests are outlined. The feasibility of a pushbroom OCM is demonstrated, and the usefulness of the concept is clearly assessed for the visible channels. A design which meets most of the essential objectives of the mission and, in particular, those which can only be achieved through the basic feature of the pushbroom, namely the dwell-time, was developed.
