The Transient Array Radio Telescope (TART) is a low-cost open-source array radio telescope consisting of 24 all-sky GNSS receivers operating at the L1-band (1.575 GHz). TART was designed as an all-sky survey instrument for detecting radio bursts, as well as providing a test-bed for the development of new synthesis imaging and calibration ...
Aperture synthesis is possible only if both the amplitude and the phase of the incoming signal are measured by each telescope. For radio frequencies, this is possible by electronics, while for optical frequencies, the electromagnetic field cannot be measured directly and correlated in software, but must be propagated by sensitive optics and interfered optically.
Very-long-baseline interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy. In VLBI a signal from an astronomical radio source, such as a quasar, is collected at multiple radio telescopes on Earth or in space. The distance between the radio telescopes is then calculated using the time difference between the ...
The Astronomical Image Processing System (AIPS) is a software package to support the reduction and analysis of data taken with radio telescopes. Developed predominantly for use with the then under-construction VLA, the generality inherent in its design allowed it to become the standard data-reduction package for most radio interferometers, including VLBI.
TRAO was established in October 1986 with the 13.7 meter Radio Telescope. It opened the new era of the millimeter-wave radio astronomy in Korea as one of the main facilities of Korea Astronomy and Space science Institute [24] (KASI). It is operated by Radio astronomy division in KASI. [25] Korean VLBI Network (KVN) Republic of Korea 22/43/86 ...
First combined image reconstruction of the event horizon of a black hole captured by the Event Horizon Telescope.[1]CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) is a Bayesian algorithm used to perform a deconvolution on images created in radio astronomy.
The Combined Array for Research in Millimeter-wave Astronomy (CARMA) was an astronomical instrument comprising 23 radio telescopes, dedicated in 2006. [1] These telescopes formed an astronomical interferometer where all the signals are combined in a purpose-built computer (a correlator) to produce high-resolution astronomical images. [ 2 ]
Mid-frequency aperture array test site for the SKA, in South Africa. Discovery in astronomy goes hand in hand with innovation in technology. ASTRON pursues a proactive programme of technical development, aimed both at providing innovative instrumentation for use on current observing facilities, and at laying the groundwork for future generations of telescopes and signal processing instrumentation.
