ASKAP Technologies: Smart Feeds
The ASKAP smart feeds project will develop the phased array feed (PAF) for ASKAP. This device provides the antenna with a wide field-of-view (FoV) by creating 30 separate (simultaneous) beams to give a FoV of 30 square degrees. Successive versions of PAFs will be tested on the Parkes Testbed Facility before the final design for ASKAP is selected.
An additional goal of the project's effort is to build the skills to enable the development of improved smart feeds for more general use within radio astronomy. This may ultimately lead to operation at higher frequencies (10 GHz and above), development of designs where cryogenic cooling of the receivers improves the system temperature (Tsys), and also lead to improvement of system aspects such as use of beamformer weights to adaptively correct for reflector distortions and pointing.
The project's activities include:
The targets are to attain:
The smart feeds project works closely with the ASKAP receivers project. LNA design requirements may be sufficiently decoupled from the smart feed electromagnetics.
