Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...
