EMBRACE will be a network of aperture arrays including a
~160m2 core located close to the existing
Westerbork Synthesis Radio Telescope
which consists of fourteen 25 m
diameter paraboloids. In addition, a smaller demonstrator
(~70m2) will be built in Nançay (France).
The core location will facilitate testing the stand-alone total
power beams of EMBRACE in comparison to a standard 25m
parabola and also to test the complex voltage beams when EMBRACE is
incorporated in a well-calibrated short-baseline (~3km)
interferometer. Operating EMBRACE in conjunction with the WSRT will
enable a range of important astronomical tests to be performed.
Total area: 160m2
(equivalent to a 14m dish)
The entire demonstrator will be made up of small tiles of
just over 1m x 1m.
The EMBRACE demonstrator system will be on a scale several hundred
times larger than The THousand Element Array (THEA), an array
designed, built and successfully proven by ASTRON to demonstrate
fundamental aspects of the aperture array concept.
Having no moving parts, the planar array is steered electronically to allow
multiple independent Fields of View.
Number of antennas:
The EMBRACE core will contain 144 tiles, ~5% of an
individual SKA station.
