Ma_MISS EQM PERFORMANCES SIMULATIONS

Abstract

This document reports on the Ma_Miss EQM performance simulations performed by mean of the Ma_Miss Radiometric Model. Performance simulations focused on the determination of the various outputs in terms of spectral power, signal and signal-to-noise ratio available at different steps in the instrument signal chain. The S/N ratio simulations have been carried out in two cases: (A) first using the “requirement values” for the optical transmittances of the various elements and connections of both TIP and Signal Link, and (B) using effective lower optical transmittances as measured on EQM parts of TIP and Signal Link. For each set of computations the final reflectance spectra have also been simulated: case (C) reflectance spectrum of olivine with “requirement values” of optical transmittances, and case (D) reflectance spectrum of olivine with “measured values” of efficiencies on EQM parts. The two sets of simulations have been compared in order to estimate the degradation of instrumental performances.
