| description |
La exploración del universo a través de radiotelescopios ha ampliado significativamente nuestro conocimiento, permitiendo el estudio de fenómenos astronómicos distantes mediante la captura y análisis de ondas de radio. Sin embargo, la efectividad de estos telescopios a menudo se ve comprometida por la interferencia de radiofrecuencia (RFI) de fuentes tanto naturales como artificiales. Para abordar este problema, desarrollamos un medidor de RFI que combina la tecnología de radio definida por software (SDR) con software de código abierto para una solución flexible y rentable. El sistema incluye una antena bicónica de banda ancha diseñada para operar en bandas VHF y UHF, una etapa de RF optimizada con amplificadores y filtros de bajo ruido y la plataforma SDR USRP B200. Los resultados experimentales demuestran la capacidad del medidor para detectar y evaluar con precisión la interferencia, con un rendimiento validado frente a un analizador de espectro profesional. Esta herramienta facilita la identificación precisa de RFI, ayudando en la selección de sitios óptimos para radiotelescopios y contribuyendo al avance de la radioastronomía. |

However, the effectiveness of these telescopes is often compromised by radio frequency interference (RFI) from both natural and artificial sources. To address this issue, we developed an RFI meter combining Software-Defined Radio (SDR) technology with open-source software for a flexible and cost-effective solution. The system includes a wideband biconical antenna designed to operate in VHF and UHF bands, an optimized RF stage with low-noise amplifiers and filters, and the USRP B200 SDR platform. Experimental results demonstrate the meter's capability to accurately detect and evaluate interference, with performance validated against a professional spectrum analyzer. This tool facilitates the precise identification of RFI, aiding in the selection of optimal sites for radio telescopes and contributing to the advancement of radio astronomy.PregradoIngeniero en ElectrónicaIngeniería Electrónica28 p.application/pdfspaUniversidad ECCIColombiaFacultad de IngenieríasDiseño e implementación de un medidor autónomo de radio interferencia en la banda de VHF y UHF basado en SDRDevelopment and Evaluation of a Software-Defined Radio-Based RFI MeterTrabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1fTextinfo:eu-repo/semantics/bachelorThesishttps://purl.org/redcol/resource_type/TPhttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/version/c_dc82b40f9837b551J.
