Simulación del radiómetro a 30 GHz de la misión Planck

Abstract

Global system performance of the 30 GHz Planck mission radiometer has been simulated to debug critical specs of individual components reducing the number of required prototypes. Special emphasis was put on trading off effective bandwidth and sensitivity. Other figures of merit evaluated were gain and noise temperature balance between Front End Module (FEM) and Back End Module (BEM) of the radiometer. Nevertheless real operation of the radiometer will be in switched mode for 1/f noise suppression, total power mode was considered for the simulation, which is enough to check the referred parameters in a quasi-static approach. The simulations were done in the frequency domain using ideal models and measurement based models.
