Radio Interferometer
A radio interferometer is an array of radio antennas or 'elements' that are used in astronomical observations simultaneously to simulate a discretely-sampled single telescope of very large aperture.
Radio Interferometer
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.
Radio Interferometer
Two or more radio telescopes that combine their signals to achieve the resolving power of a larger telescope
Ray ...
Radio interferometers consist of two or more widely separated antennas connected by transmission lines.
A radio interferometer system in which two synthesis aerials are used; one is static and utilizes the rotation of the Earth to provide a field of scan, the other is mobile. [A84]

Tran made a radio interferometer, a device that combines two radio signals. Interferometers sense radio signals more easily than a single receiver, so they can tune into signals from sources much smaller than the sun and Jupiter.
fast Fourier transformations (High Energy Astrophysics Dictionary- GSFC) A Fourier Transform is the mathematical operation that takes measurements made with a radio interferometer and transforms them into an image of the radio sky.
radio interferometer An interferometer operating at radiofrequencies. Radio interferometers are used in radio astronomy and in satellite tracking.
Located at Narrabri in northern NSW it operates as a radio interferometer.
Astronomical radio interferometers usually consist either of arrays of parabolic dishes (e.g. the One-Mile Telescope), ...
When observed with very high resolution radio interferometers, this radio core is often found to consist of two or more smaller regions, which may appear to be moving away from each other with velocities considerably greater than the speed of light.
Astronomers have created radio interferometers spanning very great distances, first across North America and later between continents.
5. You want to make a radio interferometer with the same resolution as the Hubble while operating at a wavelength of 0.21 meters. How far apart do you have to put the widest-spaced radio dishes?
1946 - Martin Ryle and his group perform the first astronomical observations with a radio interferometer
1947 - Bernard Lovell and his group complete the Jodrell Bank 218-foot (66 m) non-steerable radio telescope ...
A Fourier Transform is the mathematical operation that takes measurements made with a radio interferometer and transforms them into an image of the radio sky.
Recent work with close packed radio interferometers operating at 30 GHz has given precise measurements of the radio brightness decrement for 18 clusters, but only a few of these have adequate X-ray data.
Jennison saw greater potential for his technique in radio interferometry, and proposed that it should be tested on a three-element radio interferometer at Jodrell Bank.
The Allen Telescope Array , formerly known as the One Hectare Telescope , is a joint effort by the SETI Institute and the Radio Astronomy Laboratory at the University of California, Berkeley to construct a radio interferometer that is ...
It gets more difficult as wavelengths get shorter; it is nothing unusual for radio interferometer systems to have nodes on different continents, ...
