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. ...

ABSTRACT: Both previous radiomessages for aliens, Arecibo 1974 and Evpatoria 1999 (see http://ebe.allwebco.com/Science for details) were the logical ones and represented the binary stream of FM information, which should be arranged into two-dimensional forms to perceive by eye-like sense-organ. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... The theremin was invented 80 years ago, in 1920 by Leon Theremin. ...
