Radio Interferometry

Radio interferometry is a technique that uses multiple radio telescopes to observe the same celestial object simultaneously, improving spatial resolution by analyzing the phase differences of the signals received by each telescope. Its objective is to achieve high-precision imaging of distant celestial bodies, revealing the physical processes and structural details in the universe. This technology has significant application value in astronomical research, capable of detecting weak signals that cannot be resolved by a single telescope, and is widely used in the localization of radio sources, analysis of galaxy structures, and cosmological studies.
