Mid Frequency Aperture Array

 

The "Mid-Frequency Aperture Array" (MFAA) element of the SKA, part of the SKA Advanced Instrumentation Programme, includes the activities necessary for the development of a set of antennas, on board amplifiers and local processing required for the Aperture Array telescope of the SKA. MFAA includes the development of local station signal processing and hardware required to combine the antennas and the transport of antenna data to the station processing.

 

The overriding objectives of the MFAA Consortium are to prove the technological maturity of the Mid-Frequency Aperture Array technology, and to evaluate different concepts of front-end technology that can serve to assist in the preliminary design of the MFAA. When a concept is selected, it will then taken further in Stage 2 towards the preliminary design.


The two EMBRACE (Electronic Multibeam Radio Astronomy Concept ) stations built as part of the SKA Design Study project, located near the Westerbork in the Netherlands and at Nançay Observatory in France, are platforms that will function as test-bed for new developments and further validation of the key-technologies.

 

The SKA Mid frequency aperture array is scheduled to be deployed in the second phase of the construction of the SKA. It will cover a wide-range of radio frequencies from 400 MHz upwards. One of the key science goals for these telescopes will be their planned mission to measure the effects of dark energy on the Universe, as well as doing high speed surveys for pulsars and other radio transient events. This requires very high sensitivities, with the ability to detect very small variations in the observed signal.
