ESA ITT AO/1-8235/15/NL/RA - PM2 - Detailed Performance Models

The scope of this document is to present the detailed performance analysis of the CS-based instrument selected at the Preliminary Design Review (PDR). With reference to the Deliverable TN2, issued at the PDR, the instrument selected for the third phase of the project is: - Concept #5A - "UV-VIS hyperspectral imager with dispersive elements on orbiter", which relies on a classical CS approach addressing the reconstruction of the full image/signal. According to the SOW, the present PM2 Report includes: oDefinition of the ?analytical and numerical models. oResults of the ?performance assessment. In addition, as suggested in the conclusions of the PDR, a further configuration addressing an upgraded version of the Concept #5A was also investigated. The latter exploits the light rejected by the DMD mirrors in off-position to implement an additional channel, with the aim of extending the application field and/or the performance of the instrument.
