... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...

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. ...
