100-200 MHz sdr-based radio telescope focused on the cosmological study of the Epoch of Reionization

Radio astronomy as an observational technique used in Astronomy allows experimental validation of theoretical models based on the study of electromagnetic cosmic waves. Technically speaking, uses dedicated instrumentation (radio telescopes) to acquire such signals. The study, base on the emission of 21-cm of neutral hydrogen at frequencies between 100 and 200 MHz, permits to cover a scientific case of open study called Epoch of Reionization (EoR) in which we seek to compare physics models with experimental measurements. This paper presents simulations and measurements of the sub-systems of a 100-200 MHz radiotelescope to establish the feseability to use Software Defined Radio (SDR) technology devices as receptors for low frequency radio telescopes.
