Beamforming in Radio Astronomy

This GNU Radio flowgraph simulates a basic interferometry system with two virtual antennas receiving a signal with a slight time delay between them to model real-world light travel time. The signals pass through channel models that add noise and transmission effects, then combine to simulate the interference pattern observed in interferometry. Users can adjust parameters like signal-to-noise ratio, phase difference, and delay times to explore how these factors influence the combined signal. The flowgraph visualizes the resulting signal in the frequency domain, offering a hands-on understanding of how interferometry enhances resolution and sensitivity in radio astronomy.
