Descripció del contingut i pla d'activitats:
This thesis is devoted to the design, implementation, and characterization of a low-cost, high-flexibility radio telescope utilizing Software-Defined Radio (SDR) technology. Traditional radio astronomy instrumentation often relies on expensive, application-specific hardware that lacks the adaptability required for multi-purpose astronomical observations. By leveraging the versatility of SDR, this project aims to democratize access to radio astronomy for educational and small-scale research environments.
The system architecture consists of a parabolic reflector antenna and a high-sensitivity feedhorn optimized for observations in the range spanning from MHz to a few GHz. The signal chain incorporates a low-noise amplifier (LNA) and a bandpass filter to mitigate terrestrial interference before digitizing the signal via an RTL-SDR or similar high-bandwidth SDR platform.
The core of the project focuses on the development of a digital signal processing (DSP) pipeline. This software layer performs integration, and baseline subtraction. Calibration will be conducted using the "hot/cold" method, utilizing the ground and the empty sky as thermal references to determine the system's equivalent noise temperature.
A design requirement is that the entire system should be prepared to facilitate the incorporation of interferometry mechanisms.

Activities Plan:
1) SDR Front-end subsystems design
2) Subsystems development and integration
3) Performance system analysis
