radio interferometer | astroweb | signals from different antenna to be combined | array telescope | Type of radio telescope that relies on the use of two or more aerials at a distance from each other to provide a combination of signals from one source which can be analyzed by computer. Such an analysis results in a resolution that is considerably better than that of a parabolic dish aerial by itself because of the greater effective diameter. | ||||||||||||||||||||||||
